Does tooth whitening cause damage to your teeth or sensitivity?Professional tooth whitening, carried out by a dental professional, requires a legal prescription from a Dentist, and a maximum concentration limit in the UK. This can come as either 6% hydrogen peroxide or 16% carbamide peroxide; or a combination. Within these percentages, it is completely safe to whiten your teeth. There is no permanent sensitivity associated with tooth whitening. Sometimes people can get some sensitivity during the whitening procedure, but this can vary between patients depending on their general tolerances to sensitivity. There should be no permanent damage to your teeth and no permanent sensitivity to your teeth after tooth whitening, if it has been done properly by a dental professional. The total exposure of whitening gels to your teeth over a 3-4 week period at home through your whitening kit, is the same as the amount of acid exposure you might experience when having a single glass of Coca Cola for example.

Does composite bonding damage your teeth?No composite bonding does not damage your teeth. Although it is often considered 'reversible', there are still microscopic changes that will happen to your teeth during the bonding process. Tubules in your teeth are opened so that we can confidently bond the composite material to be strong and rigid. Therefore if this is attempted to be removed afterwards (if you want to remove it or replace it for example), there would be some microscopic changes to your teeth, which you probably would not notice with the naked, untrained eye. The composite can be removed from the teeth with minimal damage when done properly under a microscope or loupes. Therefore it is important to choose a highly skilled and trained cosmetic dentist. Composite bonding is considered to be a very safe and effective way of transforming your smile, with no permanent cutting of your teeth before hand. The tooth surface is altered chemically with a bonding agent when the composite material is being placed, but this occurs as a microscopic level which you cannot see with the naked eye. Therefore it is considered 'reversible' because your original teeth would look relatively the same if the bonding was to be removed in the future.

How long does Invisalign take?On average, most Invisalign treatments will take around 6 months to complete, providing that you wear your aligners well and for 21 hours a day. However, sometimes not all of your teeth will move exactly as planned, and this can be due to: - stubborn roots - more force being needed - poor patient compliance (eg not wearing aligners regularly enough, or not using your chewies or munchies regularly enough) and therefore additional aligners may be needed, which will then increase your Invisalign treatment time. Most smile makeover cases will start and finish completely within 9-12 months. More complex cases will obviously take longer, eg 1-2 years.

Do you have to cut the teeth down for veneers?There are 2 types of veneers; - composite veneers (which are generally added directly to the teeth without cutting anything, but it covers the full front surface of the tooth). - porcelain veneers (these are made externally at a dental lab and then fitted onto the teeth). Sometimes we can get away with no preparation veneers, if the teeth are smaller in size, have some gaps that need closing. Or we would have to make space for the veneers to be seated, particularly if you want to change the colour of teeth, size and shape of the teeth etc. Therefore some preparation of the teeth would be needed, and this is often similar to roughening the surface and adding a small margin at the border. I often like to equate this to getting your nails prepared before acrylic nails are added on, it's to ensure when the final veneer is on, it's a smooth transition between the veneer and your natural tooth. Unlike many horror stories you may have seen about teeth being cut down to pegs and 'turkey teeth', there should be minimal cutting to your teeth for professional thin porcelain veneers (which are often 0.3-0.5mm thin). And if your teeth are relatively straight and well aligned, then often less preparation or none is needed!
