How long should tooth sensitivity last?

It should only last until a maximum of four weeks after having the cavity filled. During this time, you should avoid all things that may cause sensitivity to the affected tooth. If the pain persists for longer than four weeks, or if the pain subsides and then returns after four weeks, consult your dentist. There may be something happening inside the tooth that is causing the pain.


Causes of tooth pain after fillings


Tooth sensitivity. Hot and cold food and beverages can cause your tooth to be sensitive after a filling.


Cracked fillings. If the filling that was put on your tooth is cracked or loose, it may cause some discomfort. If you suspect that the pain is caused by a filling that does not fit correctly on your tooth, schedule an appointment with your dentist to have it corrected.


Allergic reactions. Some people might have allergic reactions to the materials of the fillings used. This is why before getting any filling, inform your dentist of any allergies you might have so that the appropriate filling can be used.


Home treatments 

While waiting for the tooth sensitivity to subside, there are a few preventive steps you can take to make sure that the pain does not worsen or prolong longer than it should.


Use a soft-bristled brush. Using a toothbrush with softer bristles put much less pressure on the affected tooth.

There are many milder kinds of toothpaste and mouthwashes available to deal with the problem of sensitive teeth. There is no alcohol content in these products, so they are not too harsh for the teeth.


Gentle brushing and flossing. Put less pressure when you brush the affected tooth. You will still be able to clean the tooth well even if you do not brush it hard. Practice brushing all sides of the tooth, and also your tongue to remove all the plaque in your mouth that can agitate the affected tooth.


The sensitivity of your tooth will most likely be gone before you know it. Your dentist is there to answer any questions you might have while your tooth is on its way to full recovery. Just remember to steer clear – at least for the first four weeks – of the triggers that can cause sensitivity. Good oral health after the filling will increase the chances that the pain will go away more quickly.


Tooth pain after a filling is not unusual. If you will ever have a tooth sensitive to cold after filling, you already know what to do.
