Getting a dental filling is a routine procedure that most people will need at some point. The process usually takes one visit, lasts about an hour, and involves removing decayed tooth material and replacing it with a protective material. Without insurance, a single filling typically costs between $150 and $450, depending on the material and the tooth’s location. Most people return to normal eating and drinking as soon as the numbness wears off, which is usually within a few hours.
What Are the Steps to Getting a Filling?
The process is straightforward, but it starts before you ever sit in the dentist’s chair. You first need to schedule an exam so the dentist can confirm you have a cavity. Tooth decay does not always cause pain, especially in the early stages, so regular checkups are how most cavities get caught.
At the appointment, the dentist will numb the area around the tooth with a local anesthetic like lidocaine. You will feel a pinch when the needle goes in, but the numbing itself takes effect within a few minutes. Once the tooth is numb, the dentist uses a high-speed drill to remove the decayed portion of the tooth. You may feel vibration and hear a whirring sound, but you should not feel pain.
After the decay is removed, the dentist cleans the cavity and prepares it for the filling material. For tooth-colored composite fillings, the dentist applies the material in thin layers, hardening each one with a curing light. For amalgam (silver) fillings, the material is packed into the cavity and allowed to harden on its own. The final step is shaping and polishing the filling so it matches your bite.
The entire procedure usually takes 30 to 60 minutes for a single filling. More complex cavities, or fillings between teeth, can take longer.
How Much Does a Dental Filling Cost?
The cost of a filling depends on three main factors: the material used, the size of the cavity, and whether you have insurance. Prices vary by region and by individual dental practice, but the ranges below reflect typical US costs without insurance.
| Filling Material | Typical Cost (per tooth) | Typical Insurance Coverage |
|---|---|---|
| Amalgam (silver) | $150–$250 | Usually covered at 70–80% |
| Composite (tooth-colored) | $200–$450 | Covered at 50–80% depending on plan |
| Gold | $400–$1,200 | Often covered at 50% |
| Ceramic (porcelain) | $500–$1,500 | Often covered at 50% |
Composite fillings are the most common choice today because they match the natural color of your teeth. However, some insurance plans still classify composite fillings on back teeth as an upgrade over amalgam, meaning you may pay the difference out of pocket.
If you do not have insurance, ask the dental office about cash discounts or payment plans. Many offices offer a 5–10% discount for paying in full at the time of service. Dental schools also offer fillings at reduced rates, often 50–60% less than private practices, because the work is done by supervised students.
What Materials Are Used for Fillings?
There are several filling materials, and each has strengths and weaknesses. Your dentist will recommend one based on the location of the cavity, the size of the decay, and your budget.
Amalgam (silver) fillings have been used for over 150 years. They are extremely durable and can withstand heavy chewing forces, which makes them a good choice for molars. The main downside is appearance — they are clearly visible when you smile. Amalgam also expands and contracts with temperature changes, which can cause cracks in the tooth over time.
Composite (tooth-colored) fillings are made of a resin that is bonded directly to the tooth. They look natural and require less removal of healthy tooth structure than amalgam. The downside is that they are less durable than amalgam and may need replacement after 5–10 years, especially in large cavities on back teeth.
Gold fillings are the most durable option, often lasting 15–20 years or more. They are also the most expensive. Gold does not corrode and is well-tolerated by gum tissue. The main drawback, beyond cost, is that they require two visits because the gold is fabricated in a laboratory.
Ceramic (porcelain) fillings are tooth-colored, stain-resistant, and durable. They are more brittle than other materials and can be harder on the opposing tooth. Like gold, they typically require two visits and cost more than composite.
Glass ionomer fillings are sometimes used for children or for cavities near the gum line. They release fluoride, which helps prevent further decay, but they are not strong enough for chewing surfaces.
How Long Does Recovery Take After a Filling?
Recovery from a filling is minimal for most people. The local anesthetic wears off within 2–4 hours. Until it does, avoid eating because you could accidentally bite your cheek, lip, or tongue without feeling it.
You can eat soft foods as soon as the numbness is gone. Chewing on the side of the filling is fine for composite fillings immediately. For amalgam fillings, your dentist may advise waiting 24 hours before chewing on that tooth, because the material needs time to fully harden.
Some sensitivity to hot and cold is normal for the first few days. This usually resolves on its own. If sensitivity lasts longer than a week, or if you feel pain when biting down, contact your dentist. A filling that is too high can cause bite pain and may need a simple adjustment.
Over-the-counter pain relievers like ibuprofen or acetaminophen are usually enough if you experience any discomfort. Most people do not need any pain medication at all.
How Long Do Fillings Last?
The lifespan of a filling depends on the material and your oral hygiene habits. Amalgam fillings typically last 10–15 years. Composite fillings last 5–10 years. Gold and ceramic fillings can last 15–20 years or longer.
Your habits matter more than the material. Grinding your teeth, chewing ice, or using your teeth to open packages can shorten a filling’s lifespan. Poor oral hygiene leads to new decay around the edges of the filling, which is the most common reason fillings fail.
Regular dental checkups allow your dentist to inspect fillings for wear, cracks, or gaps. Catching a failing filling early is much cheaper than waiting until the tooth develops a new cavity underneath.
Can You Prevent Cavities and Avoid Fillings?
Yes, most cavities are preventable. The two most effective measures are brushing twice a day with fluoride toothpaste and flossing daily. Fluoride strengthens tooth enamel and can reverse very early decay before it becomes a cavity.
Diet also plays a major role. Sugary and acidic foods and drinks feed the bacteria that cause decay. It is not just how much sugar you consume — it is how often. Sipping sugary drinks throughout the day keeps your teeth bathed in sugar and acid, which is worse than eating a dessert in one sitting.
Dental sealants are a protective coating applied to the chewing surfaces of back teeth. They are highly effective at preventing cavities in the grooves of molars, where toothbrushes often cannot reach. Sealants are most commonly applied to children’s teeth, but adults can get them too if they do not already have fillings in those teeth.
Some research suggests that sugar-free gum containing xylitol can reduce cavity risk by stimulating saliva and inhibiting bacterial growth. The evidence is promising, but gum is not a substitute for brushing and flossing.
When Should You See a Dentist About a Filling?
See a dentist right away if you have tooth pain, sensitivity to sweet foods, or a visible hole or dark spot on a tooth. These are common signs of decay that needs treatment.
Do not wait for pain to become severe. By the time a cavity causes significant pain, the decay may have reached the inner pulp of the tooth, which requires a root canal rather than a simple filling. Treating a cavity early is cheaper, less painful, and preserves more of your natural tooth.
If you do not have symptoms, regular checkups every six months are still important. Many cavities develop between teeth where you cannot see them. X-rays catch these early, often before any symptoms appear.
Frequently Asked Questions
Does getting a filling hurt?
No, the procedure itself should not hurt because the dentist numbs the area with local anesthetic. You may feel a pinch from the needle and some vibration from the drill, but not pain.
Can I eat after getting a filling?
Wait until the numbness wears off, usually 2–4 hours, to avoid biting your cheek or tongue. After that, you can eat soft foods immediately, but wait 24 hours before chewing on an amalgam filling.
How long does a dental filling last?
Amalgam fillings typically last 10–15 years, while composite fillings last 5–10 years. Gold and ceramic fillings can last 15–20 years or more with good oral hygiene.
Is a filling covered by dental insurance?
Most dental insurance plans cover fillings, typically at 50–80% of the cost. Amalgam fillings are usually covered at a higher percentage than composite fillings on back teeth.
