How does a filling work? How to treat a cavity
A dental filling is a simple procedure designed to restore a tooth damaged by decay. At Archway Dental Group, the process starts with the removal of the decayed area using precise, minimally invasive techniques. Once the area is cleaned, we apply a high-quality material, such as composite resin, to rebuild the tooth. Our modern approach ensures a durable, natural-looking result that strengthens the tooth and prevents further damage. With our expertise in dental fillings in Archway, you can trust us to restore your smile effectively.

Tooth filling: does it hurt?
At Archway Dental Group, patient comfort is our top priority. Thanks to local anaesthesia and gentle techniques, most patients report that getting a filling is painless. For those who feel anxious, we offer sedation options to ensure a stress-free experience. Our team takes extra care to make your visit as comfortable as possible, explaining every step of the process to put you at ease. With us, dental care doesn’t have to be intimidating—it’s a step toward better oral health.
Dental filling costs
The cost of a dental filling depends on various factors, including the size of the cavity and the material used. At Archway Dental Group, we prioritise transparency and will discuss all options with you before starting treatment. Our finance options make it easier to access the care you need without delay.

How long does a filling last?
The lifespan of a dental filling varies depending on the material and how well it is cared for. With proper oral hygiene and regular check-ups, fillings provided by Archway Dental Group can last for many years. Our use of advanced materials ensures durability and a natural appearance, helping you maintain your restored smile for the long term. To extend the life of your filling, we recommend regular visits for preventive care.
How to Know if You Have a Cavity? Risks of an Untreated Cavity
Common signs of a cavity include tooth sensitivity, visible holes, and pain when eating or drinking. If left untreated, cavities can lead to serious complications, such as infections or tooth loss. At Archway Dental Group, we use modern diagnostic tools, including digital imaging, to detect cavities early and provide prompt treatment. Protect your oral health by addressing cavities before they worsen.
