What is Dental Filling?

A dental filling is a minor procedure that holds quite some value to itself. When a tooth is left untreated for a long time with a damaged surface, it can essentially decay the entire tooth. In the end, a person may need to get their tooth extracted in the worst-case scenario. Hence, to prevent this from happening, a dental filling is necessary.

You may or may not know whether you need a filling. This is why a dental check-up every six months is suggested. The dentist will view your teeth closer with a microscopic lens and decide on the filling.

If your dentist chooses to give you a filing, it will contain different materials. The color is identical to your actual tooth. The filling will be like your natural tooth shape. The best part about the filling is how they’ll stop the unnecessary and random toothache and provide you with relief.

Is it normal for a tooth to be sensitive after filling? Of course, it is. A dental filling can, however, cause extreme sensitivity in some patients. Although nobody expects a dental filling to last forever, it’s pretty essential for the filling to last at least a decade.

What are the Causes of Sudden Tooth Sensitivity Months after filling?

When you get a filling on your tooth, you’ll most likely receive local anesthesia from your dentist. The damaged, cavity-infected part of the tooth is scraped with different instruments thoroughly. After they apply the numbing agent, you’ll feel a tingly sensation while the filling mixture covers the tooth’s surface.

It’s usual for everyone with a filling to feel sensitive after the numbing agent wears off. Since it’s a foreign object brushing along the surface of the natural teeth, there’s an innate sensitivity that can last for a couple of weeks. If the filling is near the root or the pulp, the sensitivity can take up to four weeks to go away.

But, what about tooth sensitivity 6 weeks after filling?

Tooth sensitivity months after filling isn’t normal. Chances are, internal infection or other different causes are causing the pain. And if the toothache after filling getting worse even after 6 weeks, it’s time to be concerned.

Hence, let’s see a few of the reasons why your filling hurts even months after the filling:

Pulpitis

When there’s an inflammation inside the pulp, it’s termed pulpitis. The reason for pulpitis happening is typically bacteria invading the pulp area of your tooth. It can happen in more than one tooth and have an awful sensitivity along with pain.

Pulpitis can be of two kinds; reversible and irreversible. If the dental drilling has disturbed the pulp region, the condition will go away on its own. However, if the pulpitis occurs because of cavities or damaged tooth tissue left behind the filling, it may be irreversible. Tooth pain after filling when chewing is a noticeable symptom of pulpitis.

Can your dentist fix pulpitis?

Yes, pulpitis is fixable. If the damage is too severe, a root canal or a tooth extraction will be optimal. It would help if you got the procedures as soon as possible to make sure the inflammation doesn’t spread from one tooth to another.

Allergic Reaction

An allergy can cause pain after a dental filling to the tooth filling materials used during the procedure. If this happens, your dentist may recommend replacing the filling with a different material.

Unfortunately, it can cause tooth sensitivity years after filling. No matter if you take cold coffee or a bar of chocolate, it will hurt.

Many people are allergic to different materials present in the filling. A dental filling, although unlikely, creates an unusual sensitive feeling in the teeth for some patients. However, an allergic reaction should not persist for months normally.

Can your dentist fix an allergic reaction?

Yes, an allergic reaction is fixable through the proper medication. In extreme cases, your dentist may take out your filling, and they may do some allergic tests on you.

High Filling

After a filling procedure, your dentist will use a colored paper to see if the filling is too high. After you bite in the colored paper, the tooth is shaped like a natural one to make sure it doesn’t collide with the upper one and cause pain.

However, in some dental proceedings, the filling may be left a bit too high. When you’re not chewing on your food and the jaw is at rest, the high filling can be painful. The periodontal ligaments on your teeth can feel tender. It may make the tooth sensitivity months after filling spike up.

Can your dentist fix a high filling?

Yes, a high filling is fixable easily by having your dentist drill a bit further along into the tooth. It’s not a challenging procedure at all. Hence there’s no need to worry.

Referred Pain

Referred pain is when a surrounding tooth is causing pain to the tooth with the filling. This pain is commonly noticed in people who have an existing tooth filling. And sometimes cold sensitivity months after filling can come with it too.

Can your dentist fix referred pain?

Referred pain should go away in a few weeks on its own without any issue. However, if the pain continues for a long time, you must get a visit to your dentist.

How Long Should a Tooth Hurt After a Filling?

Tooth sensitivity is quite normal after a filling. It’s only natural for your tooth to react with a foreign object placed on top of it. However, the feeling should be more on the sensitive side and less on the “painful” side. But how long for tooth sensitivity to go away after filling?

Although it is common to have tooth sensitivity or toothache after a dental filling, the feeling should go away in two to four weeks. If there are tooth sensitivity months after filling, you must get a dental check-up from your local dentist to determine the underlying issue.

Having a toothache or tooth cold sensitivity months after filling is a big red flag.

Tooth Sensitivity Months After Filling Remedies

Before you pay a visit to your dentist, there are some remedies for tooth filling pain which you can act on by yourself. Whether it’s a sensitivity or a toothache, try the following remedies for lessening the feeling:

  • Take over-the-counter painkillers. Ibuprofen, non-steroidal inflammatory drugs, pain relievers, etc., work well. It’s important to remember not to take antibiotics without a prescription.
  • Try to have neutral temperature food and drinks. Having cold or hot food and beverages come in contact with your teeth can cause extreme sensitivity.
  • Try to chew your food voluntarily from the opposite side of the filling. Try not to put pressure on your tooth, which has fillers.
  • Avoid acidic and carbonated drinks as much as you can. Taking acidic beverages such as citric juice, wine, coffee, and more can increase the chance of filling erosion and sensitivity.
  • Try not to chew on hard foods like sugarcane sticks, energy bars, and more.
  • Maintain proper dental hygiene by brushing twice a day and flossing correctly.
  • Use toothpaste made for sensitive teeth to avoid feeling sharp teeth. But try to avoid putting soothing agent like vanila extracts if you have a broken filling.

When Do Fillings Need to Be Replaced?

A filling may not last you an entire lifetime. It’s common in most patients to have a broken filling. According to different research fields, the first symptom of having a broken filling is when you feel an unnecessary sharp pain in your tooth from having a hot/cold drink react to your tooth.

There may also be excessive painful bites that indicate a broken filing. Other symptoms to look for are gazing at the mirror, noticing the state of the filling from the surface. If you feel a sharp edge near your tongue, it most probably indicates a chipped dental filling.

There are a few other significant symptoms as well which can help you determine when your filling needs a replacement:

Cracked filling

Adult patients have cracked filling all the time. With time, as you bite on food and drink different acidic beverages, a crack may have developed slowly on the filling. Sometimes, you may feel a sharp rock-like object come off when you’re chewing food. It means a broken filling.

Is it normal for tooth to be sensitive to cold after filling? No, it’s not. If you experience tooth sensitivity months after filling, chances are, it’s a cracked filling. Bacteria may enter into the gaps and cause toothache. X-rays can determine a broken filling.

A cracked filling needs immediate dental care. You cannot fix it at home, and you will undoubtedly need a new filling done as soon as possible to avoid further tooth complications.

Toothache

A toothache is never a good sign. If there’s a crack in your tooth, there may be an underlying cavity beneath the filling. This is possible due to the filling developing microscopic holes over the years.

The bacteria may get underneath the filling and cause extreme sensitivity. Thus, it’s essential to get a dental check-up after you experience a toothache. Even if you feel sensitive after drinking hot/cold beverages, get your tooth checked as it may be a symptom of a leaky filling.

Filling discoloration

If your filling changed its color from looking natural to a hue of dark brown, it might be a symptom of the filling decaying over time. You can get it replaced for aesthetics or even for decay if your dentist suggests it.

If the age of your filling exceeds fifteen years, the best option is to get it repaired before it cracks.
