How Long Does Tooth Bonding Last?


Tooth bonding is one of the most aesthetically pleasing and time-tested options for restoring crooked or chipped teeth. Not only the modern materials used for bonding are much longer-lasting, but they also possess the capability to exactly match the shade and colour of the natural teeth, thereby becoming virtually indistinguishable from the natural ones. This article explains everything you need to know about dental bonding and how it can help you enjoy a rockstar smile.


What Is Tooth Bonding?

According to the British Academy of Cosmetic Dentistry, bonding is a procedure in which your dentist will restore the shape and function of your teeth using a resin-based, tooth coloured filling material. The BACD recommends bonding as a minimally invasive procedure to fix badly damaged teeth and blemished smiles without the need for local anaesthesia (in the majority of the cases) and extensive natural tooth removal.


How Long Will Front Teeth Bonding Last?

The clinical service life of composite bonded filings depends on various factors, such as the location of the tooth, the extent of tooth damage, eating habits, and oral hygiene status. For example, the front teeth usually do not receive as heavy biting forces as the back teeth, which are responsible for crushing the food into smaller particles. Hence, the bonded fillings on the front teeth generally last longer than on the back ones - lasting anywhere between four to eight years, depending on various factors.


Should I Get Dental Veneers Or Dental Bonding?

Your dentist is the best person to advise you regarding the type of restoration that suits your dental and aesthetic needs. However, since the veneers are prepared in the dental laboratory under controlled conditions, they have fewer structural defects and are stronger and more durable than the bonded fillings. However, they are also more expensive. If there is a minor structural or aesthetic defect in a tooth, then bonding should be sufficient. On the other hand, veneers or crowns are recommended to restore grossly damaged teeth.


Is Tooth Bonding Safe And Permanent?

Yes, dental bonding is safe. Research has shown that composite resins used in bonded fillings do not contain harmful ingredients, and bonding doesn’t cause any adverse effects. However, some people may be allergic to a few ingredients, but their concentration is generally too low to cause any severe allergic reaction.


Is Composite Bonding A Good Option For My Teeth?

Composite bonding is one of the best options for restoring damaged teeth. Whether you have a crooked or chipped tooth or wish to get rid of your teeth stains, bonded fillings can fix various restorative and cosmetic dental flaws. Unlike the unaesthetic silver amalgam fillings, composite fillings blend perfectly with your natural teeth and offer excellent aesthetics.


How Long Do Composite Fillings Last On Front Teeth?

Contemporary composite bonded filling are strong and durable. If placed by an experienced dentist, these fillings can last more than eight years with proper care. However, if you wish to maximise the clinical life of your bonded fillings some of the following practices will help:

  • Maintain optimal dental hygiene

  • Avoid eating very hard foods directly from the restored teeth

  • Ensure regular dental checkups.


Is Dental Bonding Permanent?

Dental bonding is not a permanent tooth replacement option. With time, the filling material starts to degrade and becomes porous. This makes the bonded fillings weak over time. However, the good news is that bonded filling defects can be repaired if caught timely. If there is extensive damage to the filing, your dentist may have to replace it with a fresh one.


Can Dental Bonding Be Added To The Back Of Front Teeth?

Dental bonding can be done on virtually any tooth surface. If you have tooth decay on the backside of your front teeth, your dentist will simply remove the damaged portion and then place a bonded filling over the tooth. However, it also depends on the extent of tooth decay. If there is extensive decay, your dentist may choose to restore the tooth with crowns and veneers.


Can Dental Bonding Fix Multiple Teeth Gaps Together?

In some cases, dentists use bonding for cosmetically fixing gaps between adjacent teeth. This is typically done when patients cannot afford orthodontic treatment to fix the gap and are looking for more cost-effective options. However, if the gap between the teeth is too wide, your dentist may prefer other options like porcelain veneers or crowns.


Can Dental Composite Bonding Cover Severe Fluorosis?

According to the British Fluoridation Society, fluorosis is a condition in which exposure to high fluoride levels, mainly through drinking water, occurs during tooth development. As a result, fluorosis results in hypomineralisation of the enamel, causing the teeth to appear chalky with brown stains. Fortunately, there are many ways to fix this aesthetic problem, one of them being bonded filings. Your dentist will remove the damaged tooth portion only and then place the composite filling over it to mask the underlying staining. Other options to aesthetically fix fluorosis tooth staining are porcelain veneers and crowns.
