Experiencing a Toothache After Filling? causes and treatment

posted byMuse Dental GroupOctober 26, 2021

"Toothache after filling" is common. Fillers are almost always painless. But, according to dentists, removing cavities and inserting dental fillers can cause some degree of hypersensitivity.

It is linked with the inflammatory method as part of healing. The deeper the original cavities, the greater the likelihood of postoperative toothache after filling.

Usually, the gums around the teeth will be softer. Strips or straps should be used during surgery, especially if tooth decay occurs. It is not surprising for teeth to become sensitive to cold soon after restoration.

When a doctor place filler in very deep or huge cavities, you may feel discomfort. If this discomfort is short-lived and its severity diminishes within a few weeks, the teeth should return to normal.

There is no need to worry about it; it's a normal situation. Tender toothache after filling your teeth is nothing to sweat. No doubt it's unpleasant, but your body needs time to heal; it's a natural phenomenon.

In this blog, we will be discussing the following points:

Toothache After Filling

After receiving the filling, it is not exceptional to have aches in the teeth and surrounding areas. It may feel like an abrupt sharp pain or a cold sensation, and this sensitivity can last for several days or even a week.

It is recommended that you avoid the following activities to prevent discomfort:

  • Extreme food and drink temperatures: Ice cream, frozen drinks, hot coffee, or hot food can produce pain.
  • Cold air hits your teeth: For example, when breathing through the mouth, cold air can cause discomfort for some time
  • Acid-rich foods: Such as citrus fruits, tomatoes, and coffee
  • Sugary foods: Especially sticky candies
  • Hard chewing: While eating

Toothache is usually short-term and will disappear within a few days to a week.

What are other causes of Toothache After Filling?

Fillers are used to restoring the area of cavities and reduce the discomfort linked with the cavities themselves. Several conditions can cause toothache after filling like:


Pulpitis appears when the pulp of a tooth becomes swollen, causing pain and irritation. Pulpitis rarely occurs with a small amount of filling.

It can occur in the following cases:

  • Your tooth has been injured, traumatized, cracked, or broken
  • Cavities are deep and affect the internal pulp
  • The affected tooth has had multiple fillings before

Can pulpitis be treated?

If pulpitis reaches the nerve and is damaged and cannot be preserved, root canal surgery may be required to preserve the affected tooth.

Though, if pulpitis cannot cause this if the pulp stays healthy and only mild inflammation occurs. Your dentist should also be able to cure pulpitis through filling methods or root canals. But they will decide after a thorough examination.

Multiple tooth surfaces

Also, having two different surfaces in your mouth can cause pain and irritability. Such as, if a tooth has a gold crown and your upper or lower teeth have a silver filling, it may feel odd to touch it.

Irritated nerve

An irritated nerve when placing the deep filling is not uncommon. Irritated nerves cause swelling and can cause aches.

Enamel and cementum usually shield nerves, but deep filling can reach nerve endings and produce sharp, unpleasant sensations. But irritated nerves by deep fillers cure over time.

Change in bite

If the filling is out of place or the bite is stuck , it will worsen when you chew your food. It can cause cracks in the filling.

If you don't treat improper fillings, they could break or fall out, uncovering your teeth. If the filling is not installed or positioned correctly, you should see a dentist change the shape of the filling.

Allergic reaction to tooth fillings

A few people have an allergic effect to the materials used in the filling (such as silver). Always inform your dentist if you have any allergies when discussing filling options to avoid toothache after filling.

Referred pain

It is a pain or irritability of other teeth, not the tooth that received the filling. This pain will not cause any problems with the teeth.

Dental fillings transmit the "pain signal" that the other teeth are receiving. This pain must relieve within a week or two.

How to treat Toothache After Filling?

When a person experiences the usual toothache after filling, the dentist may suggest using insensitive toothpaste.

These products have a component called potassium nitrate that prevents the feelings on the surface of the teeth from reaching internal nerve endings.

These products won't work right away but using the toothpaste twice a day should give you peace of mind and relief from pain within a few days.

In addition to sensitive toothpaste, patients with toothache after fillings may also consider trying:

  • Over-the-counter painkillers (or dentist-recommended medications)
  • Use a soft toothbrush
  • Gently brush and floss around newly filled teeth twice daily
  • Avoid sensitive drinks, hot drinks, cold drinks, and more!

When to see a dentist

The toothache after fillings should disappear within 2-4 weeks. If sensitivity does not seem to improve during this time or lasts longer than four weeks, contact your dentist.

People do not have to panic if their teeth are slightly sensitive within a few days of filling. Using home remedies and soothing toothpaste should help reduce discomfort.

Seek immediate medical attention if you experience worsening sensitivity, difficulty eating, toothache, fever, or other symptoms.


The filling is a safe and helpful way to treat tooth decay. Most fillings will last for several years. Brushing and flossing every day to take care of your teeth and regular dental checkups will help prevent future tooth decay .
