10 Causes of Tooth Sensitivity

10 Causes of Tooth Sensitivity
November 5, 2019 Adam Harwood

Tooth sensitivity can be a very uncomfortable thing to deal with. The good news is, we have some information about why you may be experiencing this – and what you can do to fix it!

Harsh brushing

It is important to always use a soft-bristled toothbrush and remember to brush gently if you are noticing that your teeth are becoming sensitive. By brushing too forcefully, you may wear away at the enamel and protective layers of your teeth.

Acidic foods

When it comes to avoiding the tooth discomfort, the first thing you should avoid it acidic foods. Some examples of these foods include lemons, limes, pickles, pineapple, tomato sauce, etc. The acidic nature of these foods can cause discomfort if the nerves of your teeth are exposed.

Whitening toothpaste

Yes, we know you want those pearly white teeth, but beware! Many brands of whitening-toothpaste can be too aggressive on your teeth. Certain chemicals in these kinds of toothpaste affect the overall quality of your teeth and some people may be more sensitive to these chemicals than others. Talk to your dentist about switching to a toothpaste that is made for sensitive teeth. There are even some whitening options in these brands as well!


Enamel may be tough, but grinding your teeth is even tougher. If you know you are someone that grinds their teeth, talk to your dentist about getting a mouthguard that will help you break this terrible habit! Or go into a local sports shop and buy a sports mouthguard – it’ll do the trick!

Gum disease

Although you might not think your gums are the culprit for your tooth sensitivity, this is a
big one. Receding gums usually come with age but also can be a result of poor oral health care. Your dentist will present you with methods to treat this disease and possibly even seal your teeth to get rid of that sensitivity.

Weak or fractured tooth fillings

When you have a weak or fractured tooth filling, bacteria have a good chance of getting in
the crevasses, which may cause enamel erosion and discomfort.

Cracked tooth

If you have a cracked tooth, you will usually know ASAP. This pain tends to get even worse than just sensitivity and usually will require a visit to the dentist as soon as you feel it.

Recent dental procedure

Tooth sensitivity is common after any dental procedure, especially after a root canal, crown placement or tooth extraction. If this pain and discomfort does not subside after a few days, it is important to contact your dentist and let them know


Flossing and brushing play a huge part in preventing plaque buildup. As plaque builds up over time, it destroys your enamel, which can lead to tooth sensitivity because of decreased protection. Don’t forget to brush twice a day, floss frequently, and visit your dentist for a cleaning twice a year.

Rinsing with mouthwash too frequently

Rinsing with mouthwash can benefit your breath, but it can be detrimental to your oral health if it’s done too frequently. Some mouthwashes contain harmful chemicals and alcohols that can hurt your teeth rather than help them. Make sure to go with the neutral fluoride rinses when choosing your next mouthwash. Or keep it simple with salt water or water with baking soda in it.
