10 Biggest Causes of Tooth Sensitivity

1. You Brush With too Much Gusto: Sometimes tooth sensitivity comes from brushing with too much force or a toothbrush with bristles that are too hard.  Over time, you can wear down the protective layers of your teeth and expose the microscopic hollow tubes, or canals, that lead to your dental nerves.  When these tubules are exposed to hot or cold, or to acidic or sticky foods, tooth sensitivity and discomfort can be the result.  The simplest solution is to switch to a toothbrush with softer bristles and to be gentler when brushing.

2. You Eat Acidic Foods: If the pathways to your nerves are exposed, acidic foods such as tomato sauce, lemon, grapefruit, kiwi, and pickles can cause pain.  Use common sense: Stick to foods that won’t cause you pain.

3. You’re a tooth grinder: Grinding your teeth can wear down the enamel, even though it’s the strongest substance in your body.  By doing so, you expose the dentin, the middle layer of the tooth, which contains the hollow tubes that lead to your nerves.  Talk to your dentist about finding a mouthguard that can stop you from grinding.  The best guards are custom-made to fit your bite.

4. You have Gum Disease: Receding gums, which are increasingly common with age (especially if you haven’t kept up with your dental health routine), can cause tooth sensitivity.  If gum disease or gingivitis is the problem, your dentist may suggest a procedure to seal your teeth along with treating the gum disease itself.

5. You Have Excessive Plaque: The purpose of flossing and brushing is to remove plaque that forms after you eat.  An excessive buildup of plaque can cause your enamel to wear away.  Again, your teeth can become more sensitive as they lose their enamel protection.  The solution is to practice good daily dental care and visit your dentist for cleanings every six months- or more frequently if necessary.

6. There is Decay Around the Edges of Fillings: As you get older, fillings can weaken and fracture or leak around the edges.  It’s easy for bacteria to accumulate in these tiny crevices, which causes acid buildup and enamel breakdown.  See your dentist if you notice this type of tooth sensitivity between visits: in most cases, fillings can be easily replaced.

7: You Choose Whitening Toothpaste: Many manufacturers add tooth whitening chemicals to their toothpaste formulas, and some people are more sensitive to them than others.  If your toothpaste could be to blame for tooth sensitivity consider switching toothpaste.

8. You’re a Mouthwash Junkie: Like whitening toothpaste, some over-the-counter mouthwashes and rinses contain alcohol and other chemicals that can make your teeth more sensitive -especially if you have exposed dentin.  Solution: Try neutral fluoride rinses- or simply skip the rinse and be more diligent in brushing and flossing.

9. You’ve Had a Dental Procedure: Teeth often become more sensitive after you’ve been in the dentist’s chair.  It’s common to have the same sensitivity  after a root canal, extraction or the placement of a crown.  If your sensitivity doesn’t disappear after a short time, another visit to your dentist is in order – it could be an infection.

10. Your Tooth is Cracked: A chipped or cracked tooth can cause pain that goes beyond tooth sensitivity.  Your dentist will need to evaluate your tooth and decide the right course of treatment, such as a crown or extraction.
