What Causes a Toothache After Flossing?

Flossing is an important part of your oral health regime, just like brushing. After brushing, flossing ensures that all the areas, specifically between the teeth, are clean and no food particle is left behind.

Should flossing hurt? The answer is no. Mild discomfort is understandable with little to no bleeding (maybe due to the technique). However, if you get sharp pain impulses, it is time to get to the root of this problem.

New To Flossing

Toothache after flossing is most commonly seen in people who are new to this process. A first-timer always has trouble with this. An appropriate flossing technique is essential. Ask your dentist to properly give an overview of using a piece of floss for oral hygiene.
There may be other grave reasons for tooth pain when you floss, like sensitivity or decay. In such cases, make sure to seek professional help.

Sensitive Teeth

Sensitivity differs from person to person. You may be prone to sensitivity because of your genetics or due to brushing too hard. If you have sensitivity, your roots are most likely exposed because of enamel loss. It is advised to use mouthwashes and toothpaste specially designed to soothe aching nerves in such cases. Fluoride toothpaste also does a great deal of healing to sensitive teeth.

Tooth Decay

It is a vicious cycle; bacteria settling on the tooth, its buildup, then cavities which later on cause tooth decay. Decay can start anywhere, between the teeth as well. The pain if you floss in that area can be intolerable.

If you spot decay, take prompt action for it.


Gingivitis makes your gums swollen and inflamed. Flossing in such a condition will be painful and lead to bleeding of the gums. It would be better to get the treatment first; then, you can easily do it to maintain oral health.

Implant Pain

Loose implantation of the crown may be why it hurts after you get done with flossing. The crown is a covering supposed to protect the sensitive inner parts of the tooth. If there is inaccurate placing or loss due to trauma, flossing will cause pain.


If you have just gotten your braces on, then pain after flossing is expected. If you think about it, whether you floss or not, your teeth are bound to be in pain because of the pressure due braces. So it just might be temporary. Hang in there!

Hard Toothbrush

A hard-bristled toothbrush with a vigorous brushing technique can wear the enamel away, exposing inner layers of the tooth leading to sensitivity. So flossing might not be the issue of your pain.

Proper Flossing Technique
  1. Take about eighteen to twenty inches of floss thread and wrap around your index fingers of both hands
  2. Strongly hold the floss thread
  3. Gently slide it between the teeth
  4. Curve it in an upside-down smile shape and start flossing up and down
  5. Repeat the same steps for the next set
