Crowns are provided under the NHS if there is a clinical need. However, tooth-coloured crowns are not available on back biting teeth. If you would like to have a crown for cosmetic reasons and you do not have a clinical need, a dentist will be able to carry out the procedure privately.
On the NHS, tooth-coloured crowns are available on teeth near the front of the mouth (from the first pre-molar tooth forwards). Many people want to have tooth-coloured or gold crowns for teeth that are further back, but these are only available privately.
