One of the most common causes of discoloured teeth is due to a 'dead tooth' or a tooth that is root filled. All of our teeth are supplied by nerve and blood supply. Now when a tooth needs a root canal treatment, this supply called the pulp is removed which can lead to the deposition of blood products within the tooth which is then absorbed by the tooth leading to a darker colour. On a back tooth, this may not have any major issue but on a front tooth is a different matter altogether!
 

A smile speaks a thousand words as the old saying goes. Sometimes, it is the little changes that really make a difference. This may not be evident to everyone but if a small enhancement gives you more confidence then this make a huge difference to ones wellbeing. 

One of the ways we can enahnce a smile is with a technique called composite bonding. Our case of the month for January 2025 is really a classic one where bonding was used to improve the smile symmetry in a subtle yet striking way.
 

To answer this question, we really need to differentiate the two treatments as they are two different treatment entirely. 

Composite bonding is an additive process. In simple terms, we carefully sculpt composite resin over the teeth in question. This can be used to treat chipped, fractured, uneven and gappy teeth. Composite can also be used to replace old fillings on front ( or back) teeth. The great advantage of bonding includes:

1. Treatment is completed in one visit; an instant smile transformation!
2. Minimally invasive. There is little, if any, drilling of the underlying teeth needed.
3. Biologically safe for the teeth and gums. There is no risk of damage to the nerve.
4. Composite can be easily maintained.
5. More affordable than porcelain veneers or ceramic crowns.
6. Composite will protect the underlying teeth from further wear and tear.
 

One of the most topical subjects at the moment is the debate between composite and porcelain for dental restorations. In terms of cosmetic dentistry, this equates to the use of composite veneers and porcelain veneers. It is important to note that composite veneers can either be made by a laboratory or placed free hand by the dentist in the chair. Porcelain veneers can only be made by a dental laboratory or within a dental practice that has the necessary technology such as computer aided design and a milling machine, otherwise know as CAD-CAM.
