Tooth Coloured Fillings

Fillings are necessary for decayed or broken teeth, and some opt to replace old silver fillings for cosmetic reasons. Tooth-colored fillings are made from composite resin which is a blend of plastic and glass particles which are now the preferred dental material over amalgam. They are bonded to the tooth using a strong adhesive and cured with a blue wave light.


Cumulus Dental uses top-quality composite resins with extensive clinical studies. Skill and precision are crucial when placing composite resin fillings, as they are highly technique-sensitive. When carefully sculpted and well-placed, these fillings can closely resemble a natural tooth.

Frequently Asked Questions


How do I know if I need a filling?

If you have a cavity, you need a filling. Signs of cavities include sensitive teeth, black or brown spots, or visible holes. It’s challenging to spot cavities on your own, so regular six month visits to the dentist are crucial. Dentists can catch small cavities early, making them easier to treat with a filling.

What happens during the filling process?

Your tooth and the surrounding area are numbed with a local anaesthetic. The decayed material is removed then the tooth is prepared with an acid gel, rinsed, bonded and filled with a composite resin. After placing and shaping the filling, it is hardened with a blue LED light. The dentist checks your bite and smoothens the surface of the filling.

Do I need local anaesthetic for a filling?

A local anaesthetic is typically administered by your dentist for a filling, but you can choose to proceed without it. In cases of small cavities or less sensitive areas, a local anesthetic may not be necessary.

Why do my fillings need to be replaced?

Dental fillings typically have a long lifespan, but eventually, they may need replacement. Continuous pressure from chewing and biting can lead to chipping, cracking, or wearing away of a filling, creating spaces for bacteria. If you observe worn or cracked fillings or experience sensitivity or pain around a filling, let your dentist know. Regular dental exams are crucial as issues with fillings can be identified early, preventing further wear or damage.

Do your fillings contain mercury?

Cumulus Dental does not use amalgam (silver-coloured) for fillings which contain mercury. We only use composite filling which is composed of plastic and glass particles in a resin matrix.

Why does my filling come loose?

Occasionally, fillings may loosen and come out. While not usually an emergency, the exposed tooth may become sensitive, and it’s important to contact the dentist promptly. If decay goes undetected and reaches beneath a filling, it can alter the tooth’s shape, causing the filling to no longer fit properly. This may result in it becoming loose and eventually falling out. If a filling falls out, a new one should be placed to ensure a snug fit and prevent decay from recurring. 

What can I do to ensure the longevity of my fillings?

With appropriate dental care, fillings can typically endure for several years. The longevity of fillings depends on factors such as their position, shape, materials used, and the pressure they endure during functioning. Larger fillings, subjected to heavier loads, may break down more swiftly than smaller ones. Dentists, during the filling placement, often have an estimate of their expected lifespan and continually monitor them during check-ups. Regular visits are essential as dentists assess for signs of weakness, cracks, decay, or discoloration in your fillings.

Why does my tooth hurt after a filling?

It’s not uncommon to experience tooth pain or sensitivity after a filling. A newly filled tooth can be more sensitive to hot and cold temperatures, as well as biting and chewing pressure. Typically, this sensitivity should subside within a week or two. If the pain persists beyond a reasonable timeframe, contact your dentist. Meanwhile, be cautious and gentle with the healing tooth.
