Why Does One Tooth Hurt When I Floss?

February 29, 2024

When one tooth hurts when you floss, it could signify a few things going on. Sometimes, food gets caught in an awkward spot, causing temporary discomfort. Other times, it might indicate something more serious, like a cavity, gum inflammation, or even a cracked tooth.

For occasional discomfort, try switching up your flossing technique and be extra gentle around that tooth. But if the pain persists or worsens, scheduling a check-up with your dentist is a good idea. They can determine what’s causing the trouble, whether it’s a minor issue or something that needs more attention.

Reasons for Toothache While Flossing

Although flossing is a part of the oral hygiene routine, it is not supposed to hurt, but it can if something is wrong with your oral health. Therefore, if one tooth hurts while flossing, it can be due to the following reasons:

  1. New at Flossing
    If you have just incorporated flossing into your oral hygiene regimen, your hands may not work correctly. You may put unnecessary pressure around one spot more than the other areas. But you are not alone. It is a common mistake. You can try changing your technique.
    Flossing aims to throw that sharp lasso between your teeth to remove the trapped bacteria or food particles, but it must be painless. Rather than being an aggressive flosser, do it gently. The pain should subside after changing the method if it doesn’t. Visit your dentist. There might be some other issue with your tooth.
  2. Tooth Decay
    Flossing and brushing kill a good amount of bacteria inside your mouth. However, some of these can still sneak in and survive. This results in decay, cavities, and infections between teeth. Sometimes, this pain occurs in one particular spot while doing the floss.
    You must also be vigilant about other symptoms of tooth damage, like sensitivity to temperatures and pain while chewing. If the pain persists or worsens. Seek medical help immediately.
  3. Sensitivity
    Brushing is crucial, but aggressive brushing is harmful to your teeth. When you apply excessive pressure while brushing, this uneven pressure can cause a specific area to become sensitive. This sensitivity is noticeable with the help of multiple symptoms. Pain while flossing is one of them.
    This happens because once the enamel is damaged, the dentin becomes exposed. Neural endings are sensitive, and even cold air can make them hurt. However, you can seek the right treatment at the dental office.
  4. Gingivitis
    If one tooth hurts while you floss, it can indicate the start of gum disease, called gingivitis. You can experience inflamed or swollen gums, redness, tenderness, and foul smell. People with gingivitis can put away brushing and flossing due to the tenderness of gums, but little do they know that brushing and flossing can heal gingivitis.
    Therefore, you must not stop and keep up with the pain in the initial stage. If the symptoms persist, contact your dental professional for a diagnosis and permanent treatment.
