This can result from old, worn out or badly designed dentistry or simply by gross neglect of teeth (visible cavities / plaque / staining).
A smile that lacks harmony, symmetry and proportion as well as any obvious signs of dental decay can be very off-putting whenever a person opens the lips.
In our cosmetic dentistry practice in the City of London EC4 we see many cases like these. They usually require a number of restorative treatments – to correct, replace and harmonise. The result can totally transform a person’s way of life.
