One of the most common places where people will require fillings is in the back teeth. This is because the chewing surfaces have fissures, where food particles and plaque can get stuck. Brushing alone does not always get into these fissures and as a result cavities can occur.
The best way to counter this problem and to reduce the need for rear fillings is to ask your City of London dentist to use a dental sealant. A dental sealant can be easily painted onto the rear teeth and is simply a plastic material that prevents food and other unwanted particles getting stuck in those hard to reach places.
As the saying goes, prevention is better than cure and this is definitely the case when it comes to oral health. Fillings repair the damage done by tooth decay and cavities, whereas a dental sealant works to prevent it.
The sealant is applied to the permanent molars, of which the first ones tend to appear around the age of 6 and the second set around the age of 12. The procedure is very simple and quick, the teeth are cleaned and a gel is applied to the teeth that are to be treated. After a few minutes the gel is washed off and the tooth dried. The sealant is then painted onto the teeth and the dentist will usually use a special light to harden the sealant, which takes about a minute.
On average the sealant will last somewhere between 5 and 10 years and can be done in clear, white or tinted.
