Most people do not realise they have tooth decay until a dentist points it out. Early decay causes no pain, and so many patients are surprised to find they need treatment. The good news is that decay that is found early usually can be conservatively treated before it becomes more serious.
The cost of tooth decay treatment in the UK can range from around £120 to £300+ for a filling, depending on the size of the cavity and the amount of tooth structure affected. However, if decay progresses deeper into the tooth, treatment costs can increase significantly. A tooth requiring root canal treatment may cost £250–£950+, while teeth that need crowns following extensive decay can cost £600–£1,050+, depending on the restoration selected.
Two patients can have decay on the same tooth, but the patient who seeks treatment earlier will probably need a simpler procedure. Routine dental examinations reveal decay before the symptoms appear, making treatment as simple and inexpensive as possible.
The cost of treatment depends largely on how far the decay has progressed before intervention takes place.

Recovery is usually straightforward, with most patients returning to normal daily activities immediately afterwards.
Your dentist assesses the extent of decay and tooth damage.
X-rays and scans may be used to detect hidden decay.
Damaged tooth tissue is removed while preserving healthy structure.
The cavity size and location determine the most suitable repair.
The tooth is restored to regain strength, function and appearance.
Guidance on oral hygiene and diet helps reduce future decay.
Decay usually spreads gradually through the tooth. What may begin as a small cavity can eventually reach deeper layers of the tooth, requiring more complex treatment. This is why the cost of tooth decay treatment is often linked to when the problem is discovered rather than the decay itself.
Yes. In fact, many cavities are identified before any symptoms appear. Routine examinations and X-rays often detect decay long before pain develops, allowing treatment to be completed while the problem is still relatively small.
Once decay reaches the nerve, a filling alone may no longer be enough. Root canal treatment may be required to remove infection and preserve the tooth. In some cases, a crown may also be recommended to strengthen the tooth afterwards.
In most cases, yes. Treating decay early is usually significantly less expensive than extracting a tooth and replacing it with a bridge, denture or implant later.
Not always. Very early enamel changes may sometimes be managed with preventive measures and monitoring. However, once a cavity has formed, restorative treatment is often recommended to stop the damage from progressing.
Preventive care helps identify small problems before they become large ones. Regular examinations and hygiene appointments are often far less expensive than treating advanced decay that has already damaged significant tooth structure.
Yes. Fillings repair existing damage but do not make a tooth immune to future decay. Good oral hygiene, regular dental visits and reducing sugar intake can help lower the risk of new cavities developing around existing restorations.
