Composite filling

Composite fillings can match the color of the tooth almost perfectly. They give great aesthetics and don’t stand out at all. Composite is recommended for all sizes of cavities and does well on front teeth.

This permanent tooth filling is cheaper than porcelain and gold but more expensive than amalgam. Chair time is about 20 minutes. Composite can last for at least 5 years and are the most popular material for cavity fillings.

Cutting-edge composites continue to evolve each year and often boast increasing long-term survivability and strength.

Amalgam filling

Amalgam is the cheapest dental filling material. The benefits include good durability and flexibility. These fillings can last 10-15 years. What’s more, they are very quick to place and won’t break or crack due to temperature changes.

The downside is aesthetics. Amalgam fillings are dark in color and can even discolour the surrounding tooth structure. More of the tooth has to be drilled away, too. There is also a small percentage of people who might be allergic to amalgam.

This material is recommended for posterior tooth restoration. It is quite flexible and doesn’t crack or burst with temperature changes.

Gold filling

In order to have a gold filling fitted, the patient has to come in for at least 2 appointments. The fillings are custom-made and need a dental cast done beforehand. Gold is biocompatible and durable. It can last over 20 years.

Gold is visible in the mouth. It can’t be said, however, that it gives poor aesthetics, as some may like the way it looks. Either way, these fillings are usually meant for small cavities.

There is a slight risk of a galvanic shock, a small electrical discharge, if a patient has more than one metal filling.

Porcelain filling

Fillings made from porcelain require a cast as well. The inlay is made in a lab, perfectly fitted to the remaining tooth structure. Porcelain matches the color of surrounding teeth.

Even though these inlays are expensive, they almost never have to be replaced. Porcelain fillings are extremely strong and durable. They usually work properly for 10-15 years, but with proper care can last even up to a lifetime. Porcelain inlays may end up costing you about the same as multiple composite fillings over time.

This type is most commonly used for back teeth with large cavities.

Temporary tooth filling

Temporary fillings can be fitted in-office. They are usually placed when patients are awaiting further procedures. Gold and porcelain inlays are a good example. A temporary filling will be put in between appointments, while the permanent one is being made at the lab.

Another situation that may require this type is when you’re waiting for a crown, when undergoing multiple root canal treatments, or in an emergency. If there is no possibility of fitting composite or amalgam, the tooth can’t stay empty. Your dentist may take you in to relieve pain and schedule you for another procedure later on.

There are also cavity DIY kits that you can purchase online and do from home. A tooth filling kit, however, will never be a long-term restoration. A homemade temporary tooth filling is meant to be used in emergencies when you don’t have access to a dentist. Sooner or later, a professional will have to remove it and place a proper one.

What is the procedure of a dental filling?

The visit may take about an hour. X-rays are a common preparatory procedure. Radiographs show the dental professional how much of the tooth has to be removed.

Anesthesia

The dentist will begin by numbing your mouth. A topical gel may be used on your gums to make an injection more bearable. A local anesthetic is the most common type for cavity fillings. This way you won’t feel any pain during the procedure.

Removing damaged material

A small drill removes decayed parts of the tooth. You will feel some pressure, but if you don’t fidget too much, this stage may only take a few minutes.

Filling

Once all the damaged material is removed, it’s time to fill in the hole. A UV lamp may be used to harden the material. You might have to wear eye protection.

Polish

The last step is evening out the surface of the tooth. You won’t feel pain and this step is less uncomfortable than the initial drilling. The dentist may ask you to bite gently or run your tongue over the dentition to make sure your bite isn’t altered and that everything is smooth.

Cavity filling cost explained

Cavity fillings cost from $150 up to $2,600. The price for cavity treatment is dependent on the material used and the number of surfaces of the tooth that are affected. Whether the tooth with the cavity is anterior or posterior also impacts the price, however, to a lesser extent.

You may need some additional procedures that will be charged separately. The most common ones include:

Scope of composite fillingAverage costCost range
One surface$200$100-$400
Two surfaces$250$150-$450
Three surfaces$325$200-$500
Four or more surfaces$375$250-$550

FAQ

How long does a cavity filling take?

The visit won’t last longer than an hour. The average time for a typical cavity is about 20 minutes.

How many cavities can be filled at once?

There is no limit. Dentists often perform multiple cavity fillings during one visit. You may, for example, need more than one in a single tooth. The only limitation is your budget or insurance plan.

Do cavity fillings hurt?

Cavities hurt when you don’t get them filled. This procedure is always performed with a local injection. This should eliminate any pain during treatment. It may not be very pleasant, but it shouldn’t hurt.

Can you get a cavity filled while pregnant?

Pregnancy is no contraindication to cavity fillings. In fact, it is recommended to have your teeth treated if you are pregnant or plan to be. Oral issues can be dangerous to your and your baby’s health.

When to replace a cavity filling?

If your filling needs to be replaced, your dentist will let you know during a bi-yearly checkup. That is why it is so important not to miss those. Signs you can look for yourself include pain and discoloration. It will obviously also be necessary if the tooth filling fell out.

Generally, composite fillings may last around 5 years, while other types last up to 15. If you suffer from bruxism, a replacement may be needed more often.

How to get rid of a cavity without a filling?

Once a cavity forms, you need to get it treated. No alternative remedy is recommended by professionals. Neglecting a cavity can lead to more serious complications and you may at some point need root canal treatment or even extraction.

Does insurance cover the costs of dental fillings?

Fillings are considered medically necessary, so there is a good chance that insurance will cover at least some of the cost. Amalgam and composite fillings are almost always covered in full. In the case of other materials, your provider might reimburse you for the amount of the amalgam filling.

More often than not there is a waiting period. If you just got your insurance, they might not cover anything for a few months. Reach out to your provider and make sure you are aware of the limitations.

The solution is to get a dental discount plan. They come with no paperwork. They work kind of like a membership, you pay a regular fee and get discounts on all types of filings. Those reductions range from 10% up to 60% and you can even use them on cosmetic treatments.

Is cavity filling cheaper than extraction?

Yes. What’s more, if you have a tooth extracted, you should also think about the costs of a restoration. Those can run into thousands.
