Save Your Tooth Using Restorative Fillings
The decayed portion of teeth, known as cavities, can start as a minor problem and eventually grow into a much larger issue. A dentist often places what’s called a filling in the cavity to prevent further tooth erosion. This treatment allows you to use the tooth as usual while preventing further decay. At The Hope Dental Care Centre, Dr. Far, and Gang Wang, can fill cavities using composite.
The Tooth Filling Process
Your dentist will first apply a local anesthetic directly into the surrounding area near the tooth to be filled. Then, he will remove the decayed hard tissue from the tooth using a drill, or air abrasion instrument.
Next, he will test or probe the area to learn if there is any residual decay. After the site is free from decay, he will prepare the space to receive the filling by cleansing the cavity of debris and bacteria.
The doctor may take a few additional steps with composite or tooth-coloured fillings since the composite is applied in layers. After completing the process, he will shape the material, trim off the excess, and polish the completed restoration.
The Filling Material Options available
We offer three filling material options for our patients, which include” gold, silver (amalgam), and composite.
Gold fillings do not corrode and can last 10-15 years or longer. They are strong enough to endure chewing pressure, and some prefer their aesthetic appeal. However, gold fillings are generally the most expensive, around ten times higher than silver, and require at least two office visits.
Silver or amalgam fillings are the least expensive option. However, like gold, they don’t match the tooth’s natural colour. These fillings also involve destroying more tooth tissue before placement. And biting, hot or cold fluids can expand or contract the filling causing possible cracks and fractures as opposed to other materials. Approximately one percent of humans are allergic to the mercury found in amalgam fillings.
Composite fillings look like your natural tooth and are bonded to the tooth for more support. They are versatile and can repair broken, chipped, and worn-down teeth. Plus, they often require less removal of tooth tissue as preparation for their placement compared to amalgam fillings.

Real Patients - Real Results
The right mandibular (lower) first molar with an old and failing amalgam (gray metal) restoration, which was replaced by composite (white) restoration under rubber dam isolation.
The right maxillary (upper) first molar with an old, deteriorating composite (white) restoration. The tooth was restored by a new composite (white) after the removal of the old filling and cavity around it.
Top View:
The right maxillary (upper) first molar was restored by amalgam (gray metal) many years ago, which had weakened the tooth structure, and created a crack that ultimately led to a fracture of the cheek half of the tooth entirely. Fortunately, in this case, the crack did not extend deep below the gumline or to bone level, so it could be restored by a direct composite (white) filling.

Restorative Fillings FAQs
Can restorative fillings be done in a single visit?
Yes, composite resin fillings can typically be completed in a single visit. The process involves removing the decay, cleaning the tooth, and applying the filling material in layers, hardened with a special light. The procedure usually takes less than an hour per tooth. Your dentist will shape and polish the filling to ensure a comfortable fit, allowing you to resume normal activities immediately after the appointment.
Do composite fillings last forever?
No, composite fillings are durable but not permanent. Depending on oral hygiene, diet, and teeth grinding, they last between five and ten years. Regular dental check-ups help detect early signs of wear, allowing timely repairs or replacements. Good oral hygiene and avoiding hard objects can help extend the lifespan of your filling. If a filling becomes worn or compromised, your dentist will recommend replacing it to prevent further tooth decay.
Can I eat immediately after getting a composite filling?
You can eat once the numbness wears off, as composite fillings harden instantly under a curing light. It’s best to start with soft foods and avoid chewing on the treated tooth until you feel comfortable. Avoid hot, cold, or sticky foods if your tooth is sensitive. Biting into hard foods immediately may cause discomfort, so following your dentist’s post-procedure recommendations will help ensure a smooth recovery.
Will a filling make my tooth more sensitive?
Some mild sensitivity is normal after getting a composite filling, particularly to hot, cold, or sweet foods. This sensitivity resolves as your tooth adjusts within a few days to weeks. If it persists or worsens, it may indicate an issue like improper fit, nerve irritation, or a deeper cavity requiring further treatment. Using toothpaste designed for sensitive teeth can help minimize discomfort.
How do I know if my old filling needs to be replaced?
Signs that a filling may need replacement include pain when chewing, increased sensitivity, or visible damage such as cracks or discoloration. Over time, fillings can wear down, allowing bacteria to enter and cause decay. Regular check-ups help monitor fillings so they can be replaced when necessary to maintain tooth health.
Can a filling fall out?
A composite filling can come loose or fall out due to wear, grinding, or new decay. Contact your dentist immediately to prevent further damage or infection. In the meantime, avoid chewing on the affected side and keep the area clean. Your dentist will assess whether the filling can be replaced or if additional treatment is necessary.
Are composite fillings strong enough for back teeth?
Modern composite resin fillings are strong enough for back teeth. Advances in materials have made them more durable and resistant to wear, even under chewing pressure. At the same time, they may not last as long as metal fillings; proper care and regular dental visits can extend their lifespan. If you grind your teeth, your dentist may recommend a nightguard.
