Chipped Teeth: Fillings and Onlays as a Quick Fix

Chipped Teeth: Fillings and Onlays as a Quick Fix

Tooth enamel is one of the strongest substances in the human body, but even it has limits. A sudden impact, ongoing pressure, or everyday habits can still cause teeth to chip or crack. Biting down on hard foods, playing contact sports without a mouthguard, or grinding your teeth while sleeping are among the most common causes of chipped teeth.

While a chipped tooth may seem like a minor issue at first, leaving it untreated can increase the risk of further damage, sensitivity, or decay. The good news is that modern dentistry offers several effective ways to repair chipped teeth quickly and restore both function and appearance.

In this article, we are going to explore options for chipped teeth, with a particular focus on white fillings and dental onlays as reliable, quick-fix solutions.

How to Fix a Chipped Tooth

The best way to treat a chipped tooth depends on several factors, including how severe the damage is, where the chip is located, and whether there is pain or sensitivity. In most cases, a chipped tooth is not considered a dental emergency unless it causes significant pain or interferes with eating or sleeping.

Even so, it is always recommended to see your dentist as soon as possible. Minor chips may only require smoothing and polishing, while more significant damage may call for restorative treatment.

Common treatment options include:

Dental inlays (fillings)

Fillings are used when a larger portion of the tooth needs to be rebuilt, restoring shape and function.

Tooth Reattachment

If the broken fragment is intact, it may be possible to reattach it. The fragment should be kept moist, ideally in milk, and brought to the dentist promptly.

Dental Bonding

Bonding uses composite or porcelain material to rebuild the missing part of the tooth. The material is shaped and hardened with a special light. Bonded restorations can last many years with proper care.

Dental Veneers

Dental veneers are thin coverings placed over the front surface of teeth to repair chips and cracks. They are strong, aesthetic, and can last for decades.

Dental Onlays

Onlays are often recommended when part of the tooth is damaged but the structure can still be preserved. They are durable and provide excellent protection.

How Long do Fillings Last?

Dental fillings are designed to be durable and can last many years, but they are not a permanent solution. Their lifespan depends on several factors, including the type of filling material used, the location of the tooth, and everyday habits such as chewing, grinding, or clenching.

Over time, constant pressure from eating and normal wear can cause fillings to weaken or develop small gaps at the edges. These gaps can allow bacteria and food particles to seep underneath the filling, leading to decay that is not always visible or painful in the early stages.

Decay beneath a filling is difficult to detect without professional examination and dental imaging. If left untreated, it can progress and reach the dental pulp, potentially resulting in infection or the need for more complex treatment.

This is why regular dental check-ups are essential, even when your teeth feel fine. Routine visits allow your dentist to monitor existing fillings, identify early signs of wear or decay, and replace or repair fillings before more serious problems develop.

Inlays and Onlays Explained

Inlays and onlays are often referred to as indirect fillings. They are custom-made by a dental laboratory and are used when a tooth is too damaged to support a standard filling but does not require a full crown.

  • Inlays are placed within the grooves of a tooth when the cusps are not damaged.
  • Onlays are used when a larger portion of the tooth is affected and may cover one or more cusps or the entire biting surface.

Both options are commonly made from composite resin and bonded to the tooth with strong dental cement. They restore the natural shape of the tooth, strengthen weakened areas, and help prevent further deterioration.

Common Dental Filling Materials

Modern dentistry offers several materials for dental fillings, each with its own advantages. The most suitable option depends on where the tooth is located, how much of the tooth structure is damaged, how visible the filling will be, and your personal preferences, including cost considerations.

Cast Gold Fillings

Gold fillings are known for their exceptional durability and resistance to wear. They can last well beyond 10 years and handle heavy chewing forces very effectively. Some patients also prefer their distinctive appearance. However, gold fillings are among the most expensive options and usually require more than one dental visit to place.

Silver Amalgam Fillings

Silver amalgam fillings are strong, reliable, and typically last up to 15 years. They are often more affordable than other materials and are well suited for back teeth where chewing pressure is highest. That said, their metallic appearance makes them more noticeable, and because they contain mercury, they may not be suitable for everyone.

Tooth-coloured Composite Fillings

Composite fillings are designed to closely match the natural colour of your teeth, making them a popular choice for visible areas. They bond directly to the tooth structure, which helps support the remaining tooth and allows for a more conservative preparation. While they are easy to place and highly aesthetic, composite fillings are generally less durable than metal options and tend to last around five years.

Your dentist will guide you through these options and recommend the most appropriate filling material based on your oral health, lifestyle, and long-term dental needs.
