What’s Inside A Tooth?

A look at the internal structure of our teeth.

If we look in the mirror and smile, our teeth appear to be individual, solid objects. Although they may look like straightforward blocks of enamel though, nothing could be further from the truth and they are far more complex structures than that. Here at Alexandra Dental Care, we feel that if people understood the structure of their teeth better, it also helps them to understand how to care for them better too. So to help our Swadlincote and Ashby patients with this, today’s blog takes a look at the three main components of a healthy tooth.

Enamel

The enamel on our teeth is the part that we all know best. Good strong enamel will help to protect our teeth from problems like decay, as well as providing much of their strength. If we keep them clean and avoid teeth staining food and drinks, it is perfectly possible to also have attractive white enamel, at least until the ageing process catches up with us. Even when this finally happens, a fast acting teeth whitening procedure can be carried out to restore it.

Dentin

The dentin layer of our teeth lies directly beneath the enamel. It is a softer layer and is also darker, more-so as we get older. If we suffer from worn or eroded enamel, it is often this layer that shows through, leading to tooth discolouration as we age. More importantly, the dentin layer is more porous than the hard enamel layer. If the enamel becomes compromised and cracks or breaks off, it exposes the dentin layer. Because of its porous nature, bacteria can then enter, eventually finding their way to the roots of the tooth, if not treated in time. Root canal infections can result.

Root canals

The root canals lie at the heart of our teeth. They are hollow and contain tiny blood vessels and also the nerves that give our teeth sensation. When these become infected via the porous dentin, the only solution is to have root canal surgery. This does not ‘heal’ the infection but involves the removal of all the infected material, including the nerves. The cavity is then filled using a s special material called gutta percha and a crown added for both appearance and strength.

As you can see from the above, the only way to protect both the dentin layer and the root canals of your teeth is to make sure that you keep your enamel in good health. Seeing a dentist at Alexandra Dental Care on a regular basis is an excellent place to start. Dental hygienist appointments are also recommended to give your teeth and gums the care that they deserve, along with diligent care at home. If you live in the Swadlincote, Ashby or surrounding areas, we are always pleased to see new patients and you can contact us by calling us on 01283 216347.
