What is Tooth Filling ?
A tooth filling is one of the most common restorative dental procedures — used to repair teeth that have been damaged by decay, minor fractures, or surface erosion. When decay is removed from a tooth, a filling material is placed to restore the tooth’s original shape, function, and structural integrity.
Tooth filling JB at QP Dental uses tooth-coloured composite resin to repair teeth damaged by decay, minor fractures, or surface erosion — typically completed in a single visit.
Composite resin bonds directly to the tooth structure, requires less removal of healthy tooth material compared to older amalgam fillings, and produces a result that blends naturally with the surrounding teeth. In most cases, a filling can be completed in a single visit
Signs You May Need a Filling
Not all cavities cause immediate pain. These are common signs that a tooth may require assessment and possible restoration.
Sharp pain or sensitivity when consuming hot, cold, or sweet food and drinks — particularly if it lingers after the source is removed.
Persistent or spontaneous aching in a tooth may indicate decay that has progressed toward the inner layers of the tooth.
A visible pit, dark discolouration, or rough surface on a tooth that you can see or feel with your tongue may be a sign of decay.
Food that regularly gets trapped in a specific tooth — especially between teeth — may point to a cavity or a failing existing filling.
Existing fillings can crack, chip, or wear over time. A damaged filling exposes the underlying tooth to decay and should be assessed promptly.
Many early cavities cause no symptoms at all. X-rays taken during a routine check-up can reveal decay before it becomes painful or difficult to treat.
How a Tooth Filling Works
A straightforward procedure typically completed in a single visit
1
Assessment
Dr Christine examines the affected tooth and, where necessary, takes a dental X-ray to assess the depth and extent of the decay. This determines whether a filling is appropriate or whether further treatment — such as a root canal or crown — may be needed.
2
Local Anaesthesia
A local anaesthetic is applied to numb the area around the tooth. This ensures the procedure is comfortable. Most patients experience little to no discomfort during the filling itself once the anaesthetic has taken effect.
3
Decay Removal
The decayed or damaged tooth material is carefully removed using a dental drill or hand instruments. Only the diseased tissue is removed — the goal is to preserve as much healthy tooth structure as possible.
4
Cavity Preparation & Cleaning
The cavity is shaped, cleaned, and disinfected to ensure no bacteria remain before the filling material is placed. A liner or base may be applied to protect the pulp, particularly in deeper cavities close to the nerve
5
Filling Placement
The composite resin filling material is applied in layers directly into the prepared cavity. Each layer is hardened using a specialised curing light before the next layer is added, building up the restoration progressively.
5
Shaping & Bite Check
Once the filling is fully placed and hardened, it is carefully shaped and polished to match the natural contours of the tooth. The bite is then checked and adjusted to ensure the upper and lower teeth come together evenly and comfortably.

Frequently Asked Questions
The procedure is carried out under local anaesthesia, so the tooth and surrounding area will be numb during treatment. Most patients are comfortable throughout. Some mild sensitivity or soreness in the area is normal after the anaesthetic wears off and typically resolves within a day or two.
A straightforward filling typically takes between 30 to 60 minutes depending on the size and location of the cavity. Your dentist will advise you on the expected duration during your consultation.
Composite (tooth-coloured) fillings generally last 7–10 years with good oral hygiene. Longevity depends on the location of the filling, bite forces, and how well you maintain your teeth. Regular check-ups help detect any wear early.
Yes — many cavities cause no pain in their early stages. Treating decay early with a small filling is simpler, less costly, and prevents the cavity from progressing to the point where a root canal or extraction may be needed.
Avoid very hot or cold foods and drinks for 24 hours. If you received a composite filling it sets immediately, but be gentle. For amalgam fillings, avoid chewing on that side for at least 24 hours. Sticky or hard foods should be avoided for a day or two.
Yes. Old silver amalgam fillings can be safely removed and replaced with composite resin fillings that match your natural tooth colour. Your dentist will assess whether replacement is clinically appropriate at your visit.
Untreated cavities worsen over time. Decay can spread deeper into the tooth, reaching the nerve and causing significant pain or infection. At that stage, a root canal or extraction may be required — both more complex and more expensive than a simple filling.
