Dental Implants Procedure, Types And Advantages

Teeth Whitening/Bleaching

Cosmetic teeth whitening is one of the most popular and minimally invasive ways to improve the appearance of your smile.

 Advances in bleaching and laser technology make it possible for you to lighten your teeth by up to eight shades in just one clinic visit.

An attractive smile can take you a long way. So what happens when your pearly whites aren't so pearly and white anymore? After all those years of eating, and smoking and drinking tea or coffee or wine, teeth can lose their brilliance.

At City Dental Hospital, we have a variety of methods for restoring a bright white smile, including porcelain veneers, composite bonding, dental implants and whitening, also known as bleaching. But, with all the advances made in general dentistry to enhance the appearance of the teeth, whitening is the easiest and effective. The whitening of teeth is safe and easy, and more affordable than ever before. Because of these reasons and more, whitening has become very popular.

Cosmetic Dentistry

Smile is the best makeover and an instant and excellent way to achieve that PERFECT SMILE is by cosmetic dentistry. Be it broken teeth/stained teeth, black gums, unsightly gaps or crooked teeth, cosmetic dentistry can fix it all in a flash, so you walk out with confidence, ready to take on the world!

Cosmetic dentistry is comprehensive oral care that combines art and science to optimally improve dental health, aesthetics and function.

In todays world, it seems that everyone wants to look young. This, of course, includes our mouths because when we smile, we show our teeth. In recent years, more people have become concerned about having teeth that are straight and free of stains, chips or other obvious flaws. 

Popular television shows that provide makeovers encourage this point of view. Print and TV advertisements for whitening agents have become very common. Many articles are written about bleaching agents and smile makeovers. As a result, people often want their teeth to be perfectly uniform and dazzlingly white. 

Dental offices have responded to consumer demand. They offer many services, including:

  • Porcelain laminates
  • Bleaching
  • Bonding
  • Replacing amalgam (silver) fillings with white fillings

According to the American Academy of Cosmetic Dentistry, about $2.75 billion a year is spent on cosmetic procedures. About 8,000 dentists are members of the academy. Virtually all dentists perform some types of cosmetic services. 

Most cosmetic procedures are not covered by dental insurance. However, procedures done to repair a cavity or replace a defective filling, crown or other tooth restoration may be covered. The cost of some cosmetic procedures can easily exceed $1,000 per tooth. Despite the cost and inconvenience, many people want a "smile makeover." They think it's just as important as having nice clothes or attractive hair. 

Older restorative materials such as gold or amalgam are durable and strong but are not tooth-colored. Newer techniques and materials allow for the placement of tooth-colored fillings.

Dentists have been doing cosmetic work for decades. But the materials that were used had serious drawbacks. For example, the early composite (plastic) resins tended to stain, chip and change color over time. This limited their use. 

New composite resins (tooth-colored fillings) are much better. Porcelain veneers cover the entire front of the tooth. They are another option when the color and shape of the teeth need improvement.

Composites are not as strong as gold or amalgam, but they have been much improved over the years. Newer composites are long-lasting and strong.

When a tooth has minor chips or a small fracture, many people choose to live with it. Others decide to have a crown (also called a cap) made and placed in the mouth over the tooth. This process is time-consuming and often expensive. However, it's often possible to "patch" minor flaws, chips or broken teeth with bonding composite resin. This can be smoothed and color-matched to the surrounding teeth. 
Computer imaging is another useful technique. It allows dentists to create "virtual restorations" on a computer screen. A patient can see what the results will look like before deciding to get cosmetic work done. This imaging technique is relatively new and is not common in dental practices.

Chipped teeth can be fixed with a technique called bonding. Your dentist can repair damaged areas by applying a "paste" made of a material called composite resin. The resin comes in a wide variety of shades to match your tooth color. First your dentist applies and shapes the plastic filling material. Then it is exposed to a special high-intensity blue light. It hardens almost instantly. The resin can be sanded, smoothed and polished until it closely matches the natural shade and shape of your tooth.

The most popular cosmetic dental procedures include:

  • Bonding front teeth
  • Whitening the teeth
  • Using tooth-colored fillings, which blend with the natural color of teeth.

Dental adhesives also have improved. Older dental materials were held in place by the shape of the tooth. Dentists had to remove part of the tooth to make sure that a filling would stay securely in place. But today's adhesives are very strong. They can hold a filling in place without the need to remove as much of the tooth.

There are many cosmetic options, depending on what you need to have done. For example:

  • Stained or discolored teeth — The enamel that covers the teeth can get stained. The underlying tooth structure (the dentin) also can get yellow over time. Bleaching is an option for healthy teeth. 
  • Chips or rough spots — These can be filled with a tooth-colored material called composite resin. This material can be chosen to match the color of your teeth. Once it's smoothed and polished, it will look virtually the same as the surrounding area. 
  • Cavities or cracks — Traditional amalgam fillings work fine in the back of the mouth. However, most people don't want to reveal a "metal mouth" when they smile. Silver amalgam also contains mercury. This can be toxic to the nervous system. Many dentists and patients prefer not to use silver amalgam. An alternative is to use tooth-colored fillings. These fillings are made of a plastic material similar to that used to repair chips or cracks. Some white fillings (direct composites) are pressed into the cavity and cured (hardened) with a special high-intensity blue light. Others are made in a laboratory and then cemented in place. These include special composites and porcelain fillings called inlays and onlays. Laboratory-made composites and porcelain fillings cost much more than amalgam fillings, but are much more attractive. They are about the same cost as gold fillings. Gold fillings are less appealing today because of their appearance. However, they are very strong and long lasting. 
  • Uneven teeth — It's not uncommon for a tooth to be slightly longer or have a different shape than its neighbors. With a procedure called recontouring, your dentist can reshape the tooth so that it's a better match. 
  • Gaps between the teeth — Small gaps can be closed by applying composite material between the teeth. For large gaps or other surface flaws, your dentist may recommend veneers. Veneers are among the most costly cosmetic procedures. They are permanently bonded to the fronts of the teeth. This gives them an entirely new appearance. Veneers are made from ultra-thin shells of porcelain that are matched to your exact tooth color. Your dentist also may refer you to an orthodontist to correct your gaps. Some people like or don't mind a gap. Others are very aware of it and want it closed. You and your dentist can determine the best treatment option. In some cases, the best option is no treatment. In others, it may be bonding, veneers or braces. 
  • Broken or crooked teeth — If a tooth has been badly broken or is structurally weak, you may need a crown. Today, crowns on front teeth are made of tooth-colored porcelain. It can appear very life-like. The crown may be all porcelain, or, more typically, porcelain with metal inside that fits over the tooth. Both types of crowns offer excellent results. Your choice depends on your bite (occlusion) and what you and your dentist prefer. 

Cosmetic procedures vary in technique and cost. Before you start a treatment plan, consider all the options and make an educated decision. Remember, these procedures cannot be reversed.

Be cautious about starting an extensive and costly elective procedure to change your appearance. If you want to change the color of your teeth, be aware that teeth are rarely pure white. You might not be satisfied to see that shade on your smile. A less-intense white may be more likely to give you the look you are seeking. 

In addition, excessive or frequent use of bleaching agents can lead to tooth sensitivity. Whitening can be done in your dentist's office or at home. If you whiten your teeth at home, be sure to follow the directions and to consult with your dentist.

Cosmetic dentistry can improve your self image, particularly if you have damaged or discolored teeth. Even simple procedures such as bleaching or bonding can be real confidence-boosters.

Smile Makeover

A smile is a powerful way of communication for a person. But if you are self-conscious about your teeth, you may tend to cover your teeth when you smile or not smile at all! This may create false impressions about you. You may be branded as non-communication, shy or even unfriendly. 

A new smile will not only clear these assumptions about you but will also help you make a greater impact - both, personally & professionally. Healthy teeth form the foundation of an appealing smile. A skillful blend of cosmetic science and art, helps your dentist "sculpt" or 'design' smile for you. 

In "SMILE DESIGN" the cosmetically enhanced teeth look more natural and last longer; as a result of improved technology and materials. 

You are a candidate for smile design if 

  • You have stained teeth or dicoloured fillings.
  • Your teeth are crowed; overlapping or crooked
  • You have missing teeth/large gaps between teeth
  • Your teeth have uneven shapes due to chipping, fractures or rough edges
  • Your teeth are uneven in length
  • In case of "GUMMY SMILE"

In "SMILE DESIGN" the overall appearance of your six upper front teeth is improved upon; since are the most visible when you smile. 

The other remaining teeth are also attended to, if they pose problems, 
The various techniques employed in "Smile Design" are as follows: 

Dental Fashion Jewelry

A dental jewel is a diamond or another stone, which can be attached to your teeth to brighten up your smile. A dental jewel can be attached to your teeth with no consequences at all. 

If you desire to endow your smile with a jewel, and the tooth to which the jewel should be attached are healthy, you can be a suitable candidate for this treatment.    

During the consultation, you decide the type of jewel and the tooth, to which the jewel should be attached. After checking the health of the selected tooth, the jewel can be attached.

The application of a tooth jewel is a completely painless procedure, which does not require any anesthesia. The procedure does not affect the enamel of the tooth, which is a big advantage.    

The jewel is attached to the tooth with an adhesive substance, and therefore, it is possible to remove it or change it without consequences.

The dental jewel can last a relatively long time, it is however limited by the stress put on the decorated tooth and dental care. If the jewel gets loose unexpectedly, it is possible to reattach it.    

Full Mouth Rehabiliation

Anyone with short, worn teeth or those that are chipped and broken throughout the mouth would be an excellent candidate.


Dentures are false teeth, made mostly of plastic, that replace missing or lost teeth. Dentures are a solution of last resort. Many people assume that they will need dentures as they age, but losing teeth is not a normal part of the aging process. If you care for your teeth well and guard against periodontal (gum) disease, you should be able to keep your teeth for a lifetime. 

Saving even a few natural teeth is often better than losing them all. Natural teeth or even parts of natural teeth can help you retain bone in your jaw. They also can act as stable supports for bridges, overdentures or removable partial dentures. Your dentist will try to save as many of your natural teeth as possible. 

Dentures can be either complete or partial. Complete dentures are made for people who have lost all of their teeth. They can be given more support by placement of implants in the bone under the denture. Partial dentures are used to replace only a few teeth. They attach to nearby teeth. 

The good news is that dentures aren't what they used to be. Newer materials and technology have allowed great improvements. Now dentists can fashion dentures that fit comfortably, appear natural and help you stay healthier. 

Denture problems still can occur, of course. But problems such as clicking, slipping, frequent gum irritation and odor may be signs that your dentures don't fit well. They may need to be adjusted, relined or remade.

Although dentures may look like your natural teeth, they cannot work like them. Simple actions such as speaking and eating may feel different. You will have to learn how to use and adjust to your dentures. For some people, this can take up to several months.

Gum Problems

The teeth remain embedded in jawbone which is covered from outside by gums. Healthy gums are coral pink in colour. They remain firmly attached to the underlying bone. Healthy gum can be identified by thin margins firmly adapting over the respective tooth and it does not bleed easily.

Impacted Teeth/Wisdom Teeth/Third Molars

Impacted teeth are unerupted or partially erupted teeth that cannot fully erupt due to:

  • Lack of space (crowding)
  • Misalignment (tooth is rotated out of position)
  • Conflicting position (another tooth has erupted over that position)
  • Ankylosis - when other causes of impaction are not corrected in a timely manner, the roots of the impacted tooth can fuse to the surrounding bone creating a tooth frozen in an unerupted or partially erupted state.

The teeth most likely to become impacted are the third molars, also known as "wisdom teeth." The first molars are also known as the 6-year molars since they generally erupt at around age 6, and the second molars are also known as the 12-year molars since they generally erupt at around age 12. If the third molars erupted normally, they might be called 18-year molars. But there is rarely enough space to fit these last teeth into the small space left behind the second molars, so the third molars often become impacted.

This panoramic x-ray shows the impacted 3rd molars (wisdom teeth). 
The upper wisdom teeth are crowding the sinus cavity and may erode the roots of the 2nd molars. The lower wisdom teeth are impacted sideways and are likely to cause crowding of the lower teeth, leading to malocclusion.

The most important thing to know about impacted teeth is that they almost always require extraction. The longer the extraction is postponed, the longer the tooth roots grow. When the tooth roots of an impacted tooth are allowed to develop, the risk of complication due to extraction increases significantly because the tooth roots may "wrap around" sensitive facial nerves. 

The risks of keeping an impacted tooth extend beyond the impacted tooth itself. Any impacted tooth will exert forces on the arch of your smile that may cause unnecessary crowding of your teeth. An impacted tooth below the gum surface may erode the roots of adjacent teeth. An impacted tooth above the gum line may create a "food trap" that is difficult to brush or floss and is likely to lead to decay.

Dental Extraction

A dental extraction (also referred to as exodontia) is the removal of a tooth from the mouth. Extractions are performed for a wide variety of reasons, including tooth decay that has destroyed enough tooth structure to prevent restoration. Extractions of impacted or problematic wisdom teeth are routinely performed, as are extractions of some permanent teeth to make space for orthodontic treatment.

Dental Fillings

Post And Core

Post and core is a procedure in which a metal component of an extensive tooth repair is required to rebuild a tooth in order to provide proper support for a crown. Post and core is a thin metal rod that is cemented into the root of a tooth. It consists of a post that fits into the root canal and a core portion that project above the gum. A new replacement crown will be cemented into position over the core. 

At times there is a situation when teeth are badly broken down after root canal treatment, a post-and-core becomes necessary. These teeth need to be built up before they can have a replacement crown fitted over them. Post-and-core fabrication is the method of choice for the build-up process. It can only be placed in a tooth that has had a root canal because the space previously occupied by the nerve is now filled. 

The dentist shapes the root canal and pulp chamber after the completion of root canal therapy. After x-ray of treated tooth has been taken, an impression of the prepared tooth will also be taken. A dental technician will then make the metal post-and-core, which the dentist will cement into the root. The post will act like an anchor for the placement of your crown. Post are usually recommended when there is inadequate support for a crown after endodontic treatment. The core and remaining tooth will be finally shaped before a replacement crown is made to fit over it. 

There are two major types of posts, like preformed ones that come in different shapes and sizes. The other one are cast posts, which are custom made in the lab from special metals and are stronger. The preformed posts take one visit and cast posts need two visits to the dental office to complete.

It is condition dependent as to which system of posts would be more suitable. More the loss of tooth structure, more chances are that the dentist from India dental clinics will prefer to use cast post instead of preformed for the weaker tooth.

Apicoectomy - Root End Surgery

A root end surgery, also known as apicoectomy (L. apex, apicis: a summit or a tip), is an endodontic surgical procedure whereby a tooth's root tip is removed and a root end cavity is prepared and filled with a biocompatible material.

Your teeth are held in place by roots that extend into your jawbone. Front teeth usually have one root. Other teeth, such as your premolars and molars, have two or more roots. The tip or end of each root is called the apex. Nerves and blood vessels enter the tooth through the apex. They travel through a canal inside the root, and into the pulp chamber. This chamber is inside the crown (the part of the tooth you can see in the mouth). 

During root canal treatment, the canals are cleaned. Inflamed or infected tissue is removed. An apicoectomy may be needed when an infection develops or won't go away after root canal treatment or retreatment.

Root canals are very complex, with many small branches off the main canal. Sometimes, even after root canal treatment, infected debris can remain in these branches. This can possibly prevent healing or cause re-infection later. In an apicoectomy, the root tip, or apex, is removed along with the infected tissue. A filling is then placed to seal the end of the root. 

An apicoectomy is sometimes called endodontic microsurgery because it is often done using an operating microscope. 


Invisalign enables you to straighten your teeth without anyone even knowing.
Using clear, removable aligners, this treatment is the “invisible” way to straighten your teeth. Using state-of-the-art equipment, a series of aligners are created in accordance with your needs. Each aligner is then worn for a period of weeks before the patient progresses to the next in the series.

Invisalign exerts mild pressure on teeth in order to manoeuvre them to their desired position.
Invisalign provides exceptional benefits to patients as it reduces mouth irritation generally associated with traditional Braces. This aspect also limits the amount of time spent in the dental chair. The Aligners are removable and therefore do not impact your dietary or oral hygiene habits.

Centenary Orthodontics is an Invisalign accredited practice. 

Not all conditions are treatable with Invisalign, our staff can advise you on this.
