Types of dental fillings can vary depending on the tooth being treated, the size of the cavity or damage, your bite, your preferences, and what your dentist recommends after an examination. This guide explains common dental filling materials, different types of tooth fillings, and the difference between direct and indirect fillings.
This article is for general information only and does not replace a personal dental assessment. The right filling material for you can only be recommended after your dentist has examined your tooth and discussed your treatment options.

Dental fillings are used to repair teeth that have been affected by decay, small fractures, wear, or minor damage. A filling helps rebuild the missing or weakened part of the tooth so it can function more comfortably and be easier to keep clean.
A filling may be recommended when a tooth has a cavity, a chipped area, a worn edge, or an older restoration that needs replacing. The aim is to restore strength, shape, comfort, and protection while preserving as much healthy tooth structure as possible.
A dentist may recommend a filling for several reasons, including:
Small cavities do not always cause pain at first, which is why routine examinations are important. Early treatment can often be simpler than waiting until a tooth becomes painful or infected.
Types of tooth fillings are usually grouped into two main categories: direct fillings and indirect fillings. The difference is mainly how the restoration is made and fitted.
Direct fillings are completed inside the mouth during one appointment, while indirect fillings or restorations are made outside the mouth and then fitted to the tooth. Your dentist will recommend the most suitable option depending on the size of the cavity, the strength of the remaining tooth, and the position of the tooth in your mouth.
Direct fillings are placed directly into the prepared tooth during the appointment. Composite resin is a common example of a direct filling material. The dentist removes decay or weakened tooth structure, places the filling material, shapes it, and checks your bite before you leave.
Direct fillings are often suitable for smaller or moderate repairs where enough healthy tooth structure remains.
Indirect fillings are made outside the mouth and then fitted to the tooth. These may include inlays, onlays, or larger ceramic or metal restorations. They can be useful when a tooth needs more support than a standard direct filling can provide.
An indirect restoration may be recommended when the damaged area is larger, when the tooth is under heavier biting pressure, or when the dentist wants to protect more of the remaining tooth structure.
Dental filling materials differ in appearance, strength, durability, cost, and how they are placed. Some materials are chosen because they look natural, while others may be selected for strength or for use in specific clinical situations.
When comparing dental filling materials, your dentist may consider:
The right material is not always the same for every tooth. A small repair on a front tooth may need a different approach from a larger restoration on a back tooth.
The materials below are commonly discussed in dentistry. Availability and suitability can vary, so your dentist will explain which options are appropriate for your individual case.
Composite resin fillings are tooth-coloured restorations made from a resin-based material. They are popular because they can be matched closely to the natural shade of your teeth.
At Roka Dental, composite restorations are listed as white fillings on the fees page. Your dentist can advise whether this type of restoration is suitable for your tooth.
Ceramic or porcelain restorations can be used for certain larger repairs, especially when strength and appearance are both important. These may be described as inlays, onlays, or other indirect restorations depending on the tooth and the amount of structure being replaced.
Gold or other precious metal restorations may be used in selected cases, usually as indirect restorations such as inlays, onlays, or crowns. They are known for durability but are more visible than tooth-coloured options.
Some dental practices may use other materials, such as glass ionomer, in selected situations. These materials can be useful for certain smaller repairs, temporary restorations, or lower-stress areas, depending on the clinical case.
At Roka Dental, your dentist will explain which materials are suitable and available for your tooth after an examination.
Amalgam fillings are silver-coloured fillings made from a mixture of metals. They have historically been used because of their strength, especially for back teeth. However, they are noticeable in the mouth, and many patients now prefer tooth-coloured alternatives where suitable.
Roka Dental’s current fees page states that amalgam restorations are not offered. If you already have an amalgam filling, your dentist can advise whether it is healthy, worn, leaking, or needs replacing for clinical reasons.
The best filling material depends on your tooth and your individual needs. Your dentist may consider:
At Roka Dental, your dentist will discuss which material and design is expected to give the most predictable result for your situation.
A standard filling may not be the best option if a tooth has lost a large amount of structure, has deep cracks, has had root canal treatment, or is under heavy biting pressure. In these cases, your dentist may discuss alternatives such as an inlay, onlay, or crown.
This is not always because the tooth is worse than expected. Sometimes a larger restoration is recommended to protect the tooth more reliably over time.
The exact process depends on the tooth and material being used, but a typical filling appointment may include:
For indirect restorations, your dentist may need to take a digital scan or impression and fit the final restoration at a separate appointment.
Many fillings are carried out with local anaesthetic so the tooth can be treated comfortably. You may feel pressure, vibration, or water spray during the appointment, but your dentist will aim to keep you as comfortable as possible.

After a filling, your mouth may feel numb for a short while. It is usually sensible to avoid eating until the numbness has worn off so you do not accidentally bite your cheek, lip, or tongue.
Fillings still need good home care and regular dental check-ups. Decay can develop around fillings if plaque and sugar exposure are not controlled.
The lifespan of a filling varies. It depends on the material, the size of the restoration, the tooth position, bite forces, diet, oral hygiene, and habits such as grinding or clenching.
Rather than relying on a fixed number of years, it is better to have fillings checked regularly. Your dentist can look for signs of wear, cracks, gaps, or decay around the edges.
Composite and ceramic restorations are usually the most natural-looking because they can be matched to the shade of your teeth.
Composite fillings are one of the most common types of white fillings. They are tooth-coloured and can be used in many visible areas.
Roka Dental’s current fees page states that amalgam restorations are not offered. Your dentist can explain suitable alternatives after examining your tooth.
Sometimes. Small chips or fractures may be repaired with a filling or composite material. Larger breaks may need an inlay, onlay, crown, or another treatment.
An old filling may need replacing if it is cracked, leaking, loose, worn, causing pain, or if decay has developed around it. Your dentist can assess this during an examination.
If a filling falls out, contact your dentist for advice. Try to keep the area clean and avoid chewing on that side if it is painful or sharp. If you have severe pain or swelling, urgent dental care may be needed.
If you have tooth sensitivity, a chipped tooth, a lost filling, or concerns about decay, Roka Dental can assess the tooth and explain your options clearly.
