Restorative dentistry covers a wide range of treatments required to repair teeth. Our services include:


Dental fillings are used to restore teeth that have been damaged by tooth decay. Tooth decay is damage that occurs when germs (bacteria) in your mouth make acids that eat away at a tooth. It can lead to a hole in the tooth, called a cavity. If not treated, tooth decay can cause pain, infection, and tooth loss.

We can help you decide which type of filling is best for you, taking into account the size and location of the cavity, your dental history, cosmetic concerns and affordability. Among the choices are:

Tooth-colored fillings

Made of resin-based composite (ceramic and plastic compounds). Because resins mimic the appearance of natural teeth, these fillings blend right in. If suitable, we are happy to replace your current silver fillings with this option.

Traditional dental fillings made of metal amalgam

Amalgam fillings are often known as silver fillings.

Dental amalgam is easy to work with and more durable than the resin-based composite, and therefore, in some cases, more appropriate for back teeth fillings. A drawback to an amalgam filling is that, unlike a resin filling, the metal is visible when you open wide.

Please note, dental amalgam has never been scientifically proven to harm us. However if you have any concerns please click here for information from the New Zealand Dental Association on the subject. We are happy to discuss the alternatives and proceed with the option of your choice.



We can rebuild it!

At Herne Bay Dental we do a lot of these because previously filled teeth are often weak or cracked due to a loss of structure from the drilling process.

Overlays cover the biting surface, splinting the cusps of the tooth together and preventing future tooth fracture. Usually we build them directly in the mouth with composite because it looks good, can be done in one visit, and does not involve a laboratory fee. However, for teeth close to the back of the mouth where greater strength is required, bonded amalgam, porcelain and gold are stronger, and more likely to last longer.


Usually we only replace existing crowns, or crown root-filled teeth, because the preparation process is quite destructive and can kill the nerve of the tooth. If we can use a more conservative procedure (bonded filling or overlay), we will. More conservative procedures usually cost a lot less than a crown, and can be done in one visit too. Sometimes however, a tooth may be very badly damaged, and the only way to fix it is a crown.

One Visit Crown (OVC)

one visit crownThe One Visit Crown is a clever new product that replaces traditional two-appointment crown procedures.

It conserves, preserves and reinforces the remaining sound tooth structure, providing a natural look as well as being more affordable.

During your consultation we can let you know if an OVC is right for you.

Full Mouth Rehabilitation

Patients with several dental problems often require a full-mouth rehabilitation process. Dr Leishman draws on both cosmetic and restorative dentistry solutions to improve the health, function, and appearance of the smile.
