Why are my teeth so Sensitive?
There are many things that can cause our teeth to be sensitive. First let’s start with the normal structure of our teeth. Teeth have three layers.
The enamel, the outermost layer, is the protection of our teeth. The enamel is hard and non porous.
Then we have the dentin, which is the 2nd layer of the tooth. The dentin is more porous because it is made up of tubules. These tubules are fluid filled and send signals to the 3rd layer of the tooth, which is the pulp.
The pulp is essentially the nerve. The enamel covers the dentin to prevent these signals being sent to the pulp. Therefore any deficiency of the enamel can cause sensitivity.
The root surfaces of the tooth are naturally more sensitive than the crown of the tooth. The root is normally covered up by our gingiva/gums so that we do not feel the sensitivity. If there are any areas of gingival recession then it is very likely to experience sensitivity.
Here are a few ways to reduce tooth sensitivity:
- Use toothpaste made for sensitive teeth
- Change the way you brush by using a softer toothbrush, by brushing more gently or by brushing for the full 2 minutes
- Avoid acidic foods and drinks, soda/pop, fruit juices, oranges, pickles, etc.
- Ask your dentist about desensitizing agents
- Stop grinding your teeth
- Talk to your dentist about receding gums
