Facts Behind Tooth Sensitivity

08 Dec , 2020

Tooth sensitivity occurs when the enamel layer of the teeth is damaged or removed due to several factors like incorrect brushing, eating of certain foods, health conditions, dryness of mouth and other intense factors like ‘bruxism’ (grinding of teeth).

If you can’t identify with what we at DentoXpert are talking about then, tooth sensitivity is the term used for the sharp ticklish yet painful feeling in one or more of your teeth when you eat something too cold or hot, or when you merely suck air into your mouth and then immediately regret it.

Here are some facts that will probably make your next sensitive encounter more informative:

The enamel layer is your best friend

The human teeth have three layers: Namely, the Pulp, the Dentin and the Enamel. Read this article to know more Facts about the development of teeth. 

The pulp forms the inner-most soft layer of the teeth where all the nerve endings of the teeth are present. It is the most delicate and sensitive layer that is protected by the other two outer layers.

The next layer is the Dentin which lies between the pulp and the enamel. The Dentin layer is what determines the colour of one’s teeth, so if you have yellow teeth, you know who is responsible for it!

The dentin layer is made up of several minerals and is protected by the enamel layer. The enamel is probably the most important layer of the teeth simply because it protects the other two layers and prevents the teeth from various other conditions like tooth sensitivity, easy breaking of teeth etc.

The reason why we took this deep tour in exploring the different layers of the teeth is because one of the major facts of tooth sensitivity is that it occurs when the enamel layer of the teeth is weakened or removed, which leaves the dentine layer of the tooth exposed which is very close to the nerve endings of the teeth.

White is not always bright

There’s a certain bias that we all have about white teeth and about how it’s always desirable. (Well, this is not something new) but this ideology does not always hold true because topical processes like teeth whitening and bleaching often weaken the enamel layer and cause sensitivity. If one visits the dentist often for processes like teeth whitening, it is important to regenerate the enamel layer with fluoride.

Do not brush your teeth after meals

That’s right! Contrary to what you have heard, do not brush your teeth right after a meal. The reason behind this is that brushing right after a meal weakens the enamel layer because of the acidic erosion that takes place. At DentoXpert, we advise individuals to brush between meals and not soon after a meal, so that you can save the precious enamel layer. It is hygienic enough if you rinse your mouth after every meal and brush between meals.

Beware of your brushing tools

It is important to use desensitising tooth paste if one is experiencing tooth sensitivity because the excessive salts present in normal toothpaste can aggravate the sensitivity or further damage the enamel if one is brushing too hard. It is also imperative to use toothbrushes with extremely soft bristles on them so that it doesn’t hurt the teeth further or damage the gums.

Tooth sensitivity is a rather common problem and can be treated easily by visiting a dentist or by trying some simple home remedies like including more fluoride in your oral diet and eating the right kind of foods that do not affect the sensitivity of your teeth.
