Decay And Fillings

As we approach Christmas and will no doubt be eating a lot more, I thought I would write a feature on what causes cavities in teeth, and give advice on the type of restorations available to rebuild damaged teeth.

What is decay?

Tooth decay is the most common dental problem that requires treatment. There are bacteria in the plaque that use the sugar in food and drinks to produce ACID, which dissolves tooth surfaces. This causes cavities i.e. decay.

What is the treatment for decay?

First and foremost, education and prevention is the key. In children, we offer fissure sealants – these are tooth-coloured sealants that help protect the vulnerable fissures on the biting surfaces of the molars and thus avoid decay. In adults, if there is a small or medium sized cavity, then fillings can be done with a laser without the need for injections or drilling. If there is a larger cavity, then a large white filling or a porcelain inlay should be considered. Gold and amalgam fillings are also available. Finally, if the decay is really deep and has reached the nerve, then root canal treatment is required. This intricate treatment is comfortable once the area has been numbed up, but requires Increased time and can be expensive. It is ideal to place a crown over a root filled tooth to protect it in the long-term.

What are the advantages of tooth coloured (white) fillings?

White fillings are bonded to the tooth substance. They are strong and long lasting. The fillings also look very natural, and there is no mercury content (compared to the silver amalgam fillings).

What are the two types of tooth coloured filling?

Porcelain inlays or overlays are precision made porcelain fillings that are securely bonded to the teeth. They are the most cosmetic and strongest white fillings available. This is because porcelain is made from ceramic material, as opposed to conventional white fillings (composites) that are resin based. They are indicated for large cavities or badly broken down teeth. For small to medium sized cavities, composite fillings are ideal. We have many shades of filling materials to match your teeth perfectly. These fillings are bonded to the teeth using a special bonding resin. We use a blue light to set the filling hard instantly so you can eat immediately. Careful attention is paid to shaping and polishing the restorations to produce an ideal and smooth finish.

What are the best ways of preventing decay?
  1. An annual clinical examination and regular X-rays are essential to detect and monitor decay.
  2. Good oral hygiene. Patients who clean their teeth well (i.e. good tooth brushing and daily flossing) should have less decay because more of the plaque (containing bacteria) is removed.
  3. Reduce the frequency of sugar intake. It is important to avoid sugary things in between meals. Each time you have something sweet to eat, the acid that is produced causes damage to the teeth for up to one hour. Therefore, the more often you have something sweet, the more decay will occur. A packet of polo mints eaten at regular intervals throughout the day can do far more damage than a bar of chocolate eaten in one go!
  4. A patient who is at risk from decay should use a fluoride mouthwash (e.g. Colgate Fluoriguard) regularly. Fluoride strengthens the tooth surface (enamel) and helps resist decay.
  5. Sugar free chewing gum. Chewing sugar free gum following a sweet meal will wash away the acid quicker by increasing the amount of saliva produced in your mouth.
  6. Avoid sugary food/drinks last thing at night. A cup of hot chocolate just before bed is not a good idea because whilst sleeping there is no saliva flow. Therefore the acid will linger on the teeth longer causing more decay.
