At a glance
A tooth filling is a dental treatment that removes decayed or damaged tooth material and replaces it with a restorative substance to restore the tooth's shape and function.
When bacteria in the mouth break down sugars, they produce acid that slowly eats through the hard outer layer of a tooth, called enamel, creating a cavity (a hole in the tooth). The dentist clears out all the softened, infected material, then fills the space with a chosen filling material. This seals the tooth against further bacterial entry and lets you chew normally again.
Medical Condition
Tooth fillings are used whenever a tooth has lost healthy structure and needs to be rebuilt to stay functional. The most common reason is tooth decay, but fillings also address other types of damage.
- Dental caries (tooth decay): cavities of any size that have not yet reached the tooth's nerve.
- Cracked or chipped teeth: small fractures caused by biting hard food, grinding, or an accident.
- Worn enamel: surface loss from teeth-grinding (bruxism) or heavy consumption of acidic food and drinks.
- Replacing old or broken fillings: fillings that have cracked, fallen out, or deteriorated over time.
- Closing small gaps or reshaping a tooth for cosmetic reasons, when the dentist judges a filling material suitable.
A filling is not suitable in every situation. Your dentist will discuss alternatives when the damage is too extensive for a filling alone.
- Decay that has reached the nerve inside the tooth usually requires root canal treatment before or instead of a filling.
- Very large cavities that leave too little healthy tooth structure may need a crown (a cap that covers the whole tooth) rather than a filling.
- A tooth that is fractured below the gumline is often better extracted than filled.
- Active gum disease (periodontitis) typically needs to be treated first, before restorative work is done.
Risks & Complications
Tooth filling is a routine procedure with a low risk of serious complications, but a few issues can arise.
- Tooth sensitivity: the filled tooth may feel sensitive to cold, heat, or pressure for days to weeks after the procedure. This usually settles on its own.
- Pain or discomfort around the filled tooth: mild aching is common in the first day or two.
- High bite: if the filling sits slightly too tall, biting down feels uneven. The dentist can adjust this in a short follow-up visit.
- Allergic reaction to filling material: rare, but some patients react to certain metals used in amalgam fillings.
- Filling fracture or detachment: a filling can crack or fall out, especially if it is large or placed under heavy biting pressure.
- Secondary decay under the filling: bacteria can re-enter if the seal breaks down over years.
- Nerve irritation: in deep cavities close to the nerve, some inflammation inside the tooth (pulpitis) can occur and, in rare cases, may require follow-up root canal treatment.
Preparation & Procedure
A standard tooth filling usually requires very little preparation from the patient. No fasting is needed before a routine filling, and most people can eat a light meal beforehand.
If you take blood thinners or any medication that affects bleeding, let the dentist know at your first appointment. You do not need to stop these on your own; the dentist will advise whether any adjustment is necessary. Informing the dentist about all allergies, especially to local anaesthetics (numbing injections) or latex, helps the team choose the safest materials. Smoking before the appointment is not forbidden, but good oral hygiene on the day, including brushing and rinsing, keeps the treatment area clean.
Before filling, the dentist typically reviews a dental X-ray (radiograph) of the affected tooth to see how deep the cavity is and whether the nerve is involved. No blood tests or general health assessments are needed for a routine filling.
The procedure itself usually follows these steps.
- The dentist examines the tooth and confirms the treatment plan with you.
- A local anaesthetic (numbing agent) is injected into the gum near the tooth so you feel no pain during the work. The injection site may be numbed first with a gel.
- Once the area is numb, the dentist uses a dental drill or, in some clinics, a laser to remove all decayed tissue from inside the cavity.
- The cleaned cavity is rinsed and dried.
- The dentist places the chosen filling material. For tooth-coloured composite resin fillings, the material is applied in layers and hardened with a blue curing light after each layer.
- The filling is shaped and polished to match the natural surface of your tooth.
- You bite down on a thin paper strip so the dentist can check that your bite is even. Any high spots are adjusted on the spot.
Aftercare
Recovery from a tooth filling is quick. Most patients leave the clinic and return to their normal day within an hour, but there are a few things to keep in mind while the tooth settles.
- Avoid eating or drinking hot or cold items until the local anaesthetic has fully worn off, usually one to three hours after the appointment, to prevent accidentally biting your cheek or burning your mouth.
- Mild sensitivity to temperature or biting pressure is normal for a few days. If sharp pain persists beyond two weeks, contact the dentist.
- With composite resin (tooth-coloured) fillings, the material is fully set as soon as you leave the chair. With amalgam (silver) fillings, some dentists advise waiting a few hours before chewing hard food on that side.
- Brush and floss normally around the filled tooth. Good daily hygiene is the main way to prevent decay from returning.
- Limit very sticky or very hard foods in the weeks after a new filling to reduce the risk of cracking or dislodging it.
- Attend your follow-up appointment if the dentist schedules one, typically within a few weeks for larger fillings.
- Regular dental check-ups, usually every six to twelve months, allow the dentist to spot any wear or secondary decay around the filling early.
Cost & What Determines It
The cost of a tooth filling varies widely depending on factors specific to your situation and the clinic you choose. Two patients with a cavity in the same tooth can face very different bills based on how far the decay has progressed and what material is used.
- Size and depth of the cavity: a small surface cavity requires less material and time than a large or deep one that nears the nerve.
- Number of surfaces involved: dentists describe cavities by how many sides of the tooth are affected. A filling covering two or three surfaces costs more than one covering a single surface.
- Filling material: amalgam (silver-coloured) is generally the least expensive option; tooth-coloured composite resin costs more; ceramic or glass-ionomer alternatives vary; gold inlays sit at the higher end.
- Hospital or clinic class: a private specialist dental clinic in a major city charges more than a general dental clinic in a smaller town, whether in Indonesia or abroad.
- Country where treatment is received: pricing structures differ significantly across countries, which is a key reason patients consider medical travel.
- Need for additional X-rays or pre-treatment scans beyond a routine check.
- Any preparatory treatments required first, such as managing active gum disease before the filling can be placed.
Most clinic packages for a tooth filling include the consultation, the local anaesthetic, and the filling procedure itself. Items that are often billed separately include dental X-rays taken specifically for this tooth, any desensitising treatment applied afterward, and follow-up adjustments if the bite needs correcting at a second visit.
BPJS Kesehatan covers basic dental fillings at registered Puskesmas and clinic providers within Indonesia, but does not cover treatment received abroad. Most Indonesian private health insurance policies also exclude overseas dental care. Patients who travel abroad for dental work therefore usually pay out of pocket or hold an international private health insurance plan that explicitly covers dental procedures overseas. Before travelling, ask the overseas clinic for a written cost estimate that lists every item, so there are no unexpected charges on the day.
Frequently Asked Questions
How many sessions does a tooth filling take?
A standard tooth filling is usually completed in a single appointment. The dentist removes the decayed part of the tooth, cleans the area, and places the filling material all in one visit. More extensive decay or multiple teeth being filled at once may require additional appointments.
Does getting a tooth filling hurt?
Most people feel little to no pain during the procedure because the dentist numbs the area with a local anaesthetic (an injection that makes the tooth and gum temporarily numb). You may feel some pressure or vibration from the dental tools, but not sharp pain. After the numbness wears off, mild soreness around the tooth is normal for a day or two.
How much does a tooth filling cost?
The cost depends on the type of filling material used, the size of the cavity, and how many teeth need to be filled. Tooth-coloured composite fillings typically cost more than older silver amalgam fillings, and private hospital or clinic fees vary widely. Requesting a written treatment plan from the dental clinic is the clearest way to know the actual price before you commit.
What should I avoid eating or doing after a tooth filling?
For the first few hours after a filling, it is best to avoid chewing on the side of the mouth that was treated, especially while it is still numb, to prevent accidentally biting your cheek or tongue. With some filling materials, your dentist may ask you to avoid very hard, sticky, or extremely hot and cold foods for a short period while the filling fully sets. Your dentist will tell you exactly what to avoid based on the material used.
