If you are in need of a filling, you may be wondering what your options are. You can choose between a tooth-coloured or metallic filling, both of which have their own benefits and drawbacks. Here at our dentist Welwyn Garden City, we often discuss the pros and cons of white fillings with our patients. In this blog post, we will go over how white fillings work and what to expect from this type of treatment.

What are white fillings and what are they made of?

White fillings are often used to fill in cavities and treat tooth decay. They are made of different materials, often composite, including plastic, glass and porcelain. At our dentist Welwyn Garden City you can choose from a variety of different types of white fillings to best match the appearance of your teeth.

How do white fillings work and how are they fitted?

White fillings are very different to metal amalgam which uses a setting metal putty. Composite fillings start out in a liquid state and once inserted into the tooth they harden over time. The resin of composite filling is cured using intense blue light.

The procedure for fitting a white filling usually takes a little longer than placing an amalgam, but the results are definitely worth it!

Tooth-coloured versus metallic finish

The benefit of having a tooth-coloured filling is that it will be much less noticeable than an amalgam filling. If you are concerned about the appearance of your teeth, then a tooth-coloured filling may be the best option for you. However, metallic fillings may be more durable and longer lasting, but that is becoming less of a factor as the technology of tooth-coloured fillings improves.

The thermal expansion of metal fillings is also something to take into consideration. As metal expands and contracts with changes in temperature, it can put stress on the tooth and eventually lead to cracking. Tooth-coloured fillings are made of materials that are more compatible with teeth, so they are less likely to cause this type of damage.

Are metal fillings safe? Do I need to have them removed?

Yes, metal fillings are perfectly safe. They have been used for many years and are a tried and tested method of filling teeth. They are the NHS’s preferred option for fillings as they are strong and long lasting.

You do not need to have metal fillings removed unless they are causing you discomfort. If you are concerned about the appearance of your metal fillings, our team may be able to replace them with tooth-coloured fillings.

Are tooth-coloured fillings safe?

Yes, tooth-coloured fillings are also safe. They are made from a type of plastic called composite resin. Composite resin is also used in other medical procedures, such as bone grafts. The UV light used to cure the resin is also safe when used for a short duration and has no harmful side effects.

Both filling methods involve drilling out the tooth to remove any decay. Our team will then clean the area and fill it. You should expect some sensitivity to hot and cold drinks for a few days after having a filling, but this will usually go away within a week or so.
