Why Is My Tooth Sensitive Near the Gumline?

Posted by AllSmiles

An upper right-side tooth is sensitive when something hard, like my fingernail or a toothpick, touches it near the gumline. However, I do not feel the sensitivity when I brush, floss, or eat. I had my dental cleaning in September, and my exam and X-rays were good. The sensitivity began about two weeks ago. I keep my six-month dental appointments to ensure nothing goes wrong because I dislike dental appointments. What can cause the sensitivity I feel? – Thanks. Levi from Queens, NY

 

Levi,

Addressing prolonged tooth sensitivity is essential. Even if the underlying cause isn’t severe, persistent irritation can lead to nerve damage and root canal treatment.

It is good that the sensitivity is limited to a specific spot and that temperature changes don’t affect it. When teeth develop localized sensitivity, a dentist can resolve it by sealing the area, similar to placing a small filling.

What Causes Tooth Sensitivity Near the Gumline?

One cause of tooth sensitivity near the gumline is natural tooth flexing, which causes tiny particles to break off. Aging, clenching or grinding teeth, chewing hard foods, and other factors can cause tooth flexing. Flexing can result in sensitivity and, if left untreated, progress to a more significant groove. Traditional fillings may not adhere well in this area, but a flexible material like microfill composite can seal the sensitive spot and alleviate discomfort.

Ask your dentist about sealing the sensitive area and potentially placing a small microfill filling. It may help resolve the issue.
