What are the layers of your teeth and how many are there?It’s true, but most people are unaware of this, and simply expect their teeth to get on with doing their job, day in, day out. But knowing a bit about how your teeth are constructed will give you a
What are the layers of my teeth you might ask. Each tooth consists of three main layers which are:
Tooth enamel is the hard outer layer of your tooth. It is the strongest substance in the human body, and mainly consists of calcium phosphate, an extremely hard mineral. When teeth are newly erupted, this layer is quite thick and white, but as we age it gradually becomes thinner as it is worn away during eating and chewing, but especially by acid erosion.
Acid erosion takes place every single day, every time we eat something. When we eat, we also provide food for bacteria in the mouth. As a little thank you for their meal, these bacteria produce acid that softens the enamel, gradually eroding it away. Your mouth remains more acidic for approximately half an hour to an hour after eating, after which time pH levels gradually return to normal as the enamel re-hardens. You can protect your teeth through making sure you wait awhile before brushing after meals until the enamel has become harder again. If the enamel is worn away then you’ll develop a cavity in your tooth, exposing the next layer.
Dentin is a much softer material that lies just underneath the enamel. Once exposed it is more easily worn away. Dentin is also pretty porous as it is made from lots of tiny tubules, which means if you eat something hot or cold then the sensations will be transmitted through the tooth, affecting the nerves, causing tooth sensitivity.
One way to deal with these sensations is to use toothpaste specially formulated for sensitive teeth. This needs to be used for a few weeks to be truly effective, as it works by blocking up the tubules in your dentin, making it less porous. At the same time, book a checkup with Midtown Dentistry as tooth sensitivity could mean you have a cavity that needs filling. If you don’t have the cavity filled, the decay will eventually reach the inner part of your tooth, and things could get painful.
The pulp chamber contains the pulp which consists of blood vessels, and nerves. The pulp extends down into the root canals of your tooth, which are right in the tooth roots. Your front teeth will only have one root, but your back teeth may have two or three. The nerves and blood vessels helped your tooth develop, but an adult tooth can survive perfectly well without them. This is just as well, as bacteria from an untreated cavity can get right into the pulp chamber, infecting the pulp. You’ll know when this happens as it can be very painful, and is treated by having a root canal. Contrary to popular belief, a root canal should be little worse than a filling, and will get rid of toothache, but it is far better to keep your entire tooth strong and healthy with regular checkups and professional cleanings at Midtown Dentistry.
