Why Is My Tooth So Sensitive After Getting a Filling?

Posted in Fillings

White resin tooth fillings are common today because they look nice and are kind to natural teeth. But if a filling is supposed to make your tooth feel better after getting a cavity, why is it so sensitive?

Your tooth houses a very secure and sterile environment. The inner chamber is filled with nerves and blood vessels. Wrapped around that are layers of dentin and enamel. Dentin has pores that allow the nerves in your tooth to pick up on temperature changes. Enamel is like insulation that keeps the sensation from being too strong.

When a cavity breaks through the protective enamel layer, it can open up your tooth to major sensitivity.

Fillings, in a way, do something similar. Your dentist has to drill away not just the decayed part of your tooth, but also a little more to help anchor the restoration.

Your tooth will have to adjust to the shock of having a large piece of itself replaced with a foreign material. For some time after you get your filling, your tooth may be unusually sensitive to things like:

  • Sugar
  • Cold temperatures
  • Air
  • Pressure

Give your tooth a week or so to see if it settles down. In response to the “leak,” your tooth’s dentin will build a thicker and more cushioned layer from the inside.

On occasion, persistent sensitivity can indicate a more serious problem. Your tooth simply may not respond well to the filling. Or, the restoration might have been insufficient, meaning you’d need a root canal or crown. Sensitivity could also indicate that your filling is too high and needs to be polished down a little more.

See your dentist if you feel the sensitivity means something’s wrong.

4 Signs You Should Update Your Fillings

Posted in Fillings

Whether composite or amalgam, all fillings will need to be replaced, sooner or later. Some patients willingly choose to swap out metal restorations for the more aesthetic white ones. It’s actually much better to proactively replace a restoration rather than to wait until it causes you pain.

Watch out for these tell-tale signs that your current dental filling is nearly done for:

  1. Dark Stain Around Your Filling

Staining is very common around old metal fillings. It may or may not hide the start of a cavity, so you should get it checked out. Even if there’s no decay yet, the discoloration may make you self-conscious about showing your teeth off in a smile.

  1. Cracks in the Tooth

Can you see any dark lines in the tooth around the filling?

Small fracture lines are the result of cumulative years of stress on the tooth and filling. Some fractures are too small to cause problems, but others are a sign that your tooth needs a new support.

  1. Sensitivity

Sensitivity usually comes and goes. But if it shows up suddenly in a spot where you have a filling, it could indicate the presence of a small fracture or cavity you can’t yet see.

  1. Missing Pieces

You can’t leave open pieces of your tooth exposed or else they could develop more decay. If your filling has partially or completely come out, then it definitely needs to be replaced.

If you’ve noticed that a particular old filling is looking a bit worn, should you get it filled or not? Put your mind at ease with a professional evaluation. Call your dentist to schedule a checkup.

Is Sensitivity After a Dental Filling Normal?

Posted in Fillings

White (composite resin) fillings are becoming the most common type of filling these days. But a common complaint that accompanies them is that of sensitivity. If you’ve just had a composite filling placed and have some sensitivity, then rest assured that this is likely normal.

Why does this happen?

What Happens with a Filling

During the filling procedure, you’re usually enjoying the effects of local anesthesia. You don’t feel everything that’s going on. When a cavity is drilled away, the sensitive inner layer of your tooth is exposed. A filling helps protect this delicate area. But your tooth has gone through quite an ordeal!

Once the anesthetic wears off, your tooth may start to ache a bit from the invasion with the drill and filling material. It’s very common for a newly filled tooth to be a little sore for a couple days.

Getting Used to the Filling

With time, your tooth naturally responds to sensitivity by reinforcing itself near the filling margin. You may at first be sensitive to cold, sweet foods, and bite pressure, but these sensitivities should fade.

You can strengthen your tooth by using plenty of fluoride after getting a filling. Fluoride helps remineralize surfaces that were weakened in the filling process.

When to Seek Help

In some cases, sensitivity is a sign that there is a serious problem that needs attention.

  • Is the sensitivity lasting for several weeks after the filling?
  • Do you experience pain every time you bite your teeth together?
  • Does sensitivity persist even after the hot/cold item is removed?
  • Do you have throbbing pain?

These issues could indicate that your tooth needs more attention. Call your dentist for specific recommendations.
