What Does A White Cavity Filling Cost?
Discovering you have a cavity is rarely welcome news. The next thought for most people, after wondering about the procedure itself, is the cost. If you need a filling, you have a choice of materials. For many, the aesthetic and health benefits of a white, or composite, filling make it the preferred option. But how much should you expect to pay? This guide provides a detailed breakdown of the cost of a white cavity filling, the factors that influence its price, and how it compares to other types of fillings.
Understanding White Cavity Fillings
A white cavity filling, known clinically as a composite resin filling, is a modern alternative to traditional metal amalgam fillings. It is made of a durable, tooth-coloured plastic and glass mixture. The primary appeal of a white filling is cosmetic. Because the material can be closely matched to the shade of your natural teeth, the filling is virtually invisible when you smile or open your mouth.
Beyond aesthetics, composite fillings offer a functional advantage. They bond directly to the tooth structure. This bonding process can help to support the remaining tooth, unlike amalgam, which simply sits in the cavity. This means the dentist may not need to remove as much healthy tooth structure to place a composite filling compared to an amalgam one. This makes white fillings a conservative and popular choice for treating tooth decay.
The Average Cost of a White Filling
In the UK, the cost of a white cavity filling in a private dental practice can vary. However, you can generally expect to pay between £100 and £300 for a single composite filling. The price is almost always higher than a comparable amalgam filling, which typically costs between £80 and £200 privately.
This price range is broad because of the number of variables involved. A tiny filling on the edge of a front tooth will cost less than a large, complex filling on a back molar. The cost includes the dentist’s time, the cost of the composite material, and any local anaesthetic required.
It is important to note that these are private costs. The options for white fillings on the NHS are more restricted, which we will cover later in this guide.
Key Factors That Influence the Price
The quote you receive from your dentist is based on several specific factors. Understanding these will help you see why there is such a wide range in potential costs.
1. Size and Complexity of the Cavity
This is the most significant cost driver. Fillings are often categorised by the number of tooth surfaces they cover. A simple filling on a single surface (e.g., the biting surface of a tooth) is the least expensive. A cavity that affects two or three surfaces (e.g., between two teeth) requires more material and more of the dentist’s time to shape and polish, increasing the price. A very large filling that rebuilds a significant portion of a broken tooth will be the most expensive.
2. Location in the Mouth
The position of the tooth matters. Fillings on front teeth are often smaller and primarily for cosmetic reasons. However, they require a high level of skill to blend seamlessly. Fillings on back molars are subject to immense chewing pressure. They need to be incredibly durable and precisely shaped to fit your bite. The technique required for these different locations can affect the cost.
3. The Dentist’s Skill and Experience
A highly experienced cosmetic dentist who has spent years perfecting the art of creating lifelike composite restorations will often charge a premium. Their expertise ensures the filling not only functions well but looks beautiful. A newly qualified dentist may offer lower prices. Many patients are willing to pay more for the certainty of a superior result, especially for a filling in a visible area.
4. Geographic Location
As with Airflow cleaning, the location of the dental practice plays a role. Prices in London and the South East of England are consistently higher than in other parts of the UK. This reflects the higher operating costs for the practice. A patient in Newcastle may pay £100 for a filling that would cost £250 in a central London clinic.
5. Additional Procedures
The filling itself is one cost. Sometimes, other work is needed. If the cavity is deep and close to the nerve, your dentist may place a protective liner or base underneath the filling to protect the nerve. This adds to the cost. Similarly, if the cavity is very large, the dentist might recommend an inlay or onlay (a custom-made filling) instead, which is significantly more expensive than a standard filling.
White Fillings vs. Amalgam (Silver) Fillings
The debate between white and silver fillings is ongoing. The table below summarises the key differences to help you decide which is right for you.
| Feature | White (Composite) Filling | Amalgam (Silver) Filling |
|---|---|---|
| Aesthetics | Excellent. Blends with natural tooth colour. | Poor. Very visible, can darken over time. |
| Tooth Preservation | Requires less removal of healthy tooth structure. | Requires more removal to create a strong lock. |
| Bonding | Bonds chemically to the tooth, providing support. | Does not bond; merely sits in the prepared space. |
| Durability | Less durable under extreme chewing forces; may wear or chip over 5-7 years. | Extremely durable; can last 10-15 years or more. |
| Sensitivity | May cause temporary sensitivity to hot and cold. | Conducts heat and cold, which can cause ongoing sensitivity. |
| Cost | Higher. Typically £100 – £300. | Lower. Typically £80 – £200 privately. |
Important Note: Composite fillings are technique-sensitive. They require a completely dry environment to bond successfully. For very deep cavities or in patients with poor oral hygiene, an amalgam or other restorative option like a crown may still be recommended by your dentist. The best choice is a decision to be made together with your dental professional.
The Cost of White Fillings on the NHS
The rules for white fillings on the NHS are specific. The NHS aims to provide treatment that is clinically necessary to secure oral health. For most back teeth (molars and premolars), the NHS will typically provide an amalgam filling because it is durable and cost-effective. You cannot usually request a white filling on a back tooth on the NHS simply for cosmetic reasons.
White fillings are available on the NHS in the following circumstances:
- For front teeth (incisors and canines): The NHS will provide white fillings for these teeth, as they are in the aesthetic zone.
- For back teeth in specific cases: A dentist may provide a white filling on a back tooth if they believe an amalgam filling would be clinically unsuitable, but this is uncommon.
The cost of an NHS filling is not based on the material. The NHS uses a banded charging system.
- A filling falls into Band 2 treatment, which covers fillings, root canals, and extractions.
- The current cost for Band 2 treatment is £73.50 in England. This is a set fee, regardless of the number of fillings you need or the material used (where clinically appropriate).
This means if you are eligible for a white filling on the NHS, you will pay the Band 2 fee, which is significantly cheaper than going private. However, your choices are limited, and you may not get a white filling on a back tooth.
How to Save Money on White Fillings
Dental care is an investment, but there are ways to manage the cost of white fillings effectively.
- Maintain Excellent Oral Hygiene: The most effective way to save money on fillings is to never need them. Brushing twice daily with fluoride toothpaste, flossing, and limiting sugary snacks will help prevent the cavities that require fillings in the first place.
- Attend Regular Check-ups: Catching a small cavity early is much cheaper than treating a large one. A small filling costs less and is simpler to place. Regular check-ups allow your dentist to spot and treat issues early.
- Ask About Payment Plans: Many private dental practices offer finance options, such as 0% interest payment plans, for treatment costs. This allows you to spread the cost over several months, making it more manageable.
- Consider a Dental Plan: Paying a monthly fee for a dental membership plan at a private practice often gives you a discount on treatments like fillings, sometimes up to 10-20% off.
- Compare Prices: Dental fees are not uniform. You are entitled to request a written treatment plan and cost estimate from your dentist. You can then compare this with other local practices.
What to Expect During the Procedure
Knowing what happens during a white filling placement can ease any anxiety. The process typically involves:
- Anaesthesia: The dentist will numb the area around the affected tooth with a local anaesthetic to ensure your comfort.
- Preparation: The decayed part of the tooth is removed using a dental drill. The remaining tooth structure is then cleaned and shaped.
- Bonding: The tooth is kept dry. A mild acid gel is applied to roughen the surface, helping the filling bond.
- Application: The dentist applies the composite resin in layers. A special blue light is used to harden each layer.
- Shaping and Polishing: Once all layers are placed, the dentist will trim, shape, and polish the filling to ensure it fits your bite comfortably and looks natural.
The entire procedure for a single filling usually takes between 30 and 60 minutes.
Frequently Asked Questions (FAQ)
Q: How long do white fillings last?
A: With excellent care, you can expect a white filling to last between 5 and 10 years. They are less durable than amalgam fillings, which can last much longer. The lifespan depends on the size of the filling, its location, and your chewing habits.
Q: Are white fillings safe?
A: Yes, they are very safe. Composite resin is a biocompatible material that has been used in dentistry for decades. Unlike amalgam, it contains no mercury, which is a concern for some patients.
Q: Does it hurt to get a white filling?
A: The procedure is generally painless because your mouth will be numbed with a local anaesthetic. You may feel pressure or vibration from the drill, but not pain. After the anaesthetic wears off, the tooth may feel slightly sensitive for a day or two.
Q: Can I replace my old silver fillings with white ones?
A: Yes, this is a very common procedure. Many patients choose to have their old, unsightly amalgam fillings replaced with natural-looking composite. The cost is the same as getting a new white filling. You should discuss the risks and benefits with your dentist, as removing amalgam can sometimes lead to temporary sensitivity.
Q: How soon can I eat after getting a white filling?
A: Because the filling is hardened with a light, it is fully set immediately. You can eat and drink as soon as the anaesthetic has worn off. It is best to avoid very hard or sticky foods for the first 24 hours to allow your bite to settle.

Conclusion
The cost of a white cavity filling in the UK is a premium over traditional amalgam, but it buys you significant aesthetic and structural benefits. Ranging from £100 to £300, the price reflects the size, location, and the skill required to place it. While NHS options are available for front teeth, private treatment gives you the full choice and a highly cosmetic result that can protect your smile for years to come.
