Tooth-Coloured or Amalgam Fillings? What You Should Know
Tooth-coloured composite fillings have become the standard in many practices, but amalgam is still discussed. Here is an honest comparison and advice on replacing old fillings.

A dental filling is a material placed in a tooth to restore it after decay or damage has been removed. The two best-known materials are amalgam, the traditional silver-coloured filling, and composite, a tooth-coloured resin. At Alanya Dental Help, our dental clinic in Alanya, we work with aesthetic tooth-coloured fillings and are often asked how they compare with the older amalgam type. Here is a clear overview.
What is an amalgam filling?
Amalgam is a mixture of metals, including silver, tin, copper and mercury, which are bound together in a stable alloy. It has been used for well over a century and is known for being durable and relatively forgiving to place. Its main drawbacks are its dark colour, which is clearly visible, and the fact that the tooth usually has to be shaped in a specific way to hold the filling in place, sometimes removing more healthy tooth structure.
Concerns about mercury and environmental impact have led many countries, including the European Union, to phase down or restrict the use of amalgam. Intact amalgam fillings, however, are generally not considered a reason for removal on health grounds alone.
What is a composite filling?
Composite is a tooth-coloured material made of resin and fine filler particles. It is applied in layers, bonded to the tooth with an adhesive and hardened with a special light. Because it bonds directly to the tooth, the dentist can often preserve more natural tooth structure. It can also be matched closely to the shade of your teeth, so the filling blends in.
Composite is also versatile. Besides filling cavities, it can be used to repair small chips, close minor gaps or reshape slightly uneven edges, a technique known as bonding. This makes it a useful option for small cosmetic improvements without the need for veneers or crowns.
Comparing the two
- Appearance: composite is tooth-coloured; amalgam is silver-grey
- Tooth preservation: composite often allows a more conservative preparation
- Bonding: composite bonds to the tooth; amalgam is held mechanically
- Placement: composite is more technique-sensitive and needs a dry working area
- Durability: both can last many years when placed well and cared for
For very large cavities or teeth with significant damage, a filling may not be the best option at all. An inlay, onlay or crown can sometimes protect the tooth better. Your dentist will recommend what is most appropriate.
Should old amalgam fillings be replaced?
Replacing an intact, well-functioning amalgam filling is usually not necessary for health reasons, and removing it means drilling away some tooth structure. Replacement is typically considered when the filling is cracked, leaking, has decay underneath or when a patient prefers a tooth-coloured result for aesthetic reasons, particularly on visible teeth. When replacement is chosen, it should be done carefully, with suitable precautions.
If you are combining dental treatment in Turkey with a visit to the coast, replacing old fillings with aesthetic fillings in Alanya can often be done in one or a few appointments, depending on the number of teeth. Your dentist in Alanya will examine the teeth, take X-rays if needed and suggest a sensible order of treatment.
Caring for your fillings
Whichever material you have, fillings last longest when the surrounding tooth stays healthy. Brush twice a day with fluoride toothpaste, clean between the teeth daily, limit frequent sugary snacks and drinks and attend regular check-ups. Composite fillings can pick up some surface staining from coffee or tea over time, which can often be polished during a routine visit.
After a new filling, the tooth may feel slightly sensitive to cold or pressure for a few days. If the filling feels high when you bite, or if sensitivity persists or gets worse, contact your dentist, as a small adjustment usually solves the problem quickly.

Frequently Asked Questions
Are tooth-coloured fillings as strong as amalgam?
Modern composite materials are durable and suitable for many fillings, including on back teeth. Their lifespan depends on the size of the filling, your bite and your oral hygiene. For very large cavities, other restorations may be recommended.
Is it safe to keep my amalgam fillings?
Intact amalgam fillings are generally not considered a reason for removal on health grounds alone. If a filling is damaged or you prefer a tooth-coloured result, your dentist can discuss replacement.
Does getting a filling hurt?
Fillings are usually placed under local anaesthesia, so you should feel little more than pressure and vibration. Some teeth may be slightly sensitive for a few days afterwards, which normally settles on its own.
