10 Common Reasons of Tooth Sensitivity

By Garden Oaks Dental Centre November 16, 2018

Sensitive Teeth
There are many different reasons why our teeth get sensitive and there have been many discoveries over the years as to what causes it, how and why. Tooth sensitivity can be uncomfortable causing sensitive reactions when eating and drinking hot/cold foods/drinks. It can also make one struggle to brush their teeth fully and the sensation of the brush against their teeth is cringing and even painful.

Too Many Acidic Foods

There is nothing wrong with eating foods high in acidic such as lemon, grapefruit, tomato sauce, kiwi and pickles however these foods can actually affect your teeth negatively by exposing your nerves and causing them to become sensitive. Eat these foods in moderations and ensure if you do consume them that you are not eating too much of one or the other.

Brushing Too Hard

When you think your brushing your teeth hard and your teeth are benefiting, you are wrong. Brushing your teeth too hard with force, with a hard bristled toothbrush can affect your teeth by removing and wearing down the protective layers on your teeth, and exposing too much microscopic hollow tubes and canals that are rooted to your dental nerves – which ultimately causes the sensitivity.

When the tubes more open an exposed the temperatures turns to extreme measure when dealing with acidic or sticky foods that cause tooth sensitivity and an uncomfortable feeling in the teeth and mouth. It is advised that you switch your toothbrush to one with soft bristles that can still get around your teeth and hard to reach areas, but also be gentle on your teeth when brushing.

You Grind Your Teeth

If you grind your teeth for whatever reason the teeth can lose its enamel and protection layers, wearing down the enamel eventually and exposing the dentin, which is in the middle layer of the tooth that has hallow tubes, leading to your nerves. When the teeth are exposed the enamel is wore out and can cause sensitivity an pain if grinding your teeth excessively and often. To prevent teeth grinding you can consult with you dentist to provide you with a mouth guard that will allow you to stop grinding your teeth and can fit your bite shape, targeting the issue head on.

You Use Whitening Toothpaste

Even though tooth whitening toothpaste is supposed to make your teeth brighter and mask the teeth flaws, the toothpaste itself has many harsh chemicals within that can cause sensitivity within the teeth and cause discomfort, especially when the toothpaste has whitening agents in them that causing more issues; find an alternative of product that does not contain these chemicals if you need to continue using the whitening paste.

You Use Too Much Mouthwash

Mouthwash can play a big role in teeth sensitivity and much like whitening toothpaste, it contains chemicals that can be harmful and contains alcohol that does not benefit the teeth and in turn makes them more sensitive. Try using neutral fluoride products instead and see if that reduces sensitivity. Cutting back on how often you use mouthwash it also a great way to reduce sensitive and damaged teeth overtime.
