What is cosmetic bonding and how much does it cost?

A common question we are asked is what is cosmetic bonding? The term itself does not mean a great deal and is not self explanatory. Well, I will try to explain as best as I can in simple terms and how the treatment is actually completed.


Cosmetic bonding involves the adding of a very aesthetic white filling to one or several of your teeth to make them look nicer. For example, if there is a chip on the edge of one of your teeth or it is worn down or there are gaps this can be corrected with cosmetic bonding.

The beauty of this technique is that we do not need to drill away any tooth to provide the treatment in the majority of cases. On occasion, some sharp edges or thick enamel may need to be removed prior to the bonding but this would be very minimal. Therefore, cosmetic bonding is reversible! Is that not great? A cosmetic treatment that can be reversed should you wish. I have never been asked to remove any bonding as of yet, but there is always a first time I guess!

If we look back a few years to the time of Extreme Makeover (remember that program?), virtually all of the cases involved a smile makeover using porcelain veneers and crowns. These look beautiful, no doubt. However, to make a porcelain veneer or crown especially, we have to cut the teeth down a great deal to make space for the porcelain. This is destructive and removes virtually all of the enamel from the tooth. Tooth enamel is the hardest tissue in the body and protects the biological aspects of the tooth such as the dentine (inner surface) and nerve area. Therefore, the tooth will be more prone to problems in the future without question. Now there is a time and place for porcelain veneers and crowns but, in my opinion, not on virgin teeth and with a minimal preparation as possible.

My point is therefore, that with a technique like cosmetic bonding, there is NO risk at all to the underlying tooth. The worst that could happen is that it chips, stains or becomes discoloured. Disaster! Not quite; the bonding can simply be replenished without fuss.


There are a few simple steps, which I will share with you now:

  1. The tooth is washed with an acid etch of phosphoric acid 30% for 15-30 seconds. This sounds harsh but enamel is a mineral. It can take it. The etch enhances the bonding.
  2. A bonding resin is placed over the tooth and is activated by a light. We use LED these days which generates less heat that the old halogen lights.
  3. The white filling material is then layered over the tooth sequentially and set with the light. I use Empress Direct and GC G-aenial as my preferred composites.
  4. We may need to use certain cords, clear strips, wedges in between the teeth to create a sound margin to the tooth.
  5. Once the tooth is build back up, it is contoured to size and polished in a few steps with lots of water.

The bite is checked and the final polished is completed.

Sounds simple? Well, it is. However, it takes a few years to get really good at cosmetic bonding. As with everything in life, the more you do of something, the better you get.


The technique for teeth gap filling is similar to above but we want to fill gaps between teeth rather than enhance the appearance of a single or multiple teeth. In this case, I advise a very simple mock up where we can add the cosmetic bonding directly to the tooth/teeth to fill the space and show you how the bonding would look prior to actual treatment. As long as the proportions of the teeth remain natural, the result can be incredible. On occasion, it just does not look right especially if a single tooth is widened too much. In this case, it may be that orthodontic treatment is needed or minimal preparation porcelain or composite veneers.


The price will vary at different dental practices. The typical cosmetic bonding cost in the UK is between £200-350 per tooth. We charge £230 per tooth. Compared to porcelain veneers, porcelain crowns or even composite veneers or crowns, this is cost effective and non invasive. It is a treatment I highly recommend. After all, we were born with lovely tooth enamel. Why strip it all away when there is an alternative that is aesthetic, non invasive and more cost effective?

You can see what a difference the treatment can have. Our client was delighted as the gap had bugged her for ages. Within three quarters of an hour, we had closed the space. What's more is that after a few weeks, the area looks even better as the gum line adapts around the teeth and bonding.

Case of the Month October 2021- Invisalign, whitening and bonding

Our case of the month for October was a simple yet effective one involving three of our favourite techniques: Invisalign, tooth whitening and cosmetic bonding. Crowding of teeth is so common, we would probably say the majority of the population suffer some form of mis alignment of some sort. Luckily, modern day treatments mean that teeth straightening is actually a simply and pain free process. In our case, we used Invisalign Lite which is the 'middle of the road' version which typically takes less than 6 … READ MORE

Case of the Month September 2021- E Max Veneers

Our case of the month for September 2021 was a simply stunning one using ultra minimally invasive E max veneers. Our client disliked her front teeth composite bonding which had discoloured, worn and chipped over time. Although teeth bonding is a superb treatment, there are disadvantages compared to porcelain such as those mentioned above. Porcelain will not stain or change colour and it is far more durable than composite. However, in the past, porcelain needed considerable preparation to create space for th… READ MORE

Case of the Month August 2021- Social 6 lingual brace, teeth whitening and cosmetic bonding

Our case of the month for August was a straight forward one but effective. In many cases, we get asked to correct one or two teeth which really bothers our patient. Most of the time, this is perfectly feasible using modern day cosmetic dental techniques such as lingual braces and cosmetic bonding. For our case, one tooth had slipped behind the others and was in cross bite with the lower teeth. This is where the upper tooth actually sits on the inside surface of the lower tooth when closed. This is not desir… READ MORE

Case of the month June 2021- closing space with bonding

Our case of the month for June 2021 was one where spaces were closed using cosmetic bonding or teeth bonding. Often there are spaces between teeth which are either natural, developmental, after orthodontic treatment or following a trauma. One of the simplest ways to close the spaces is via bonding. Tooth bonding is a non invasive treatment where the tooth is added to using composite white filling material. In the case of closing gaps, there is absolutely no need to cut the tooth at all. The treatment is car… READ MORE
