1. Teeth whitening
How long does it take?: About one hour.
Follow-up
How it works: The patient is fitted with a tailor-made mouth guard which they take home to England with them. The patient wears the mouthguard filled with whitening gel which is worn each night for around three weeks. This does not harm the teeth but slightly changes the composition of the dentine - the part of a tooth that is hard, contains calcium and lies underneath the enamel - making it appear whiter.
How long does it take?: Two to three weeks.
How long does it last?: Between three and six months.
Cost of tooth whitening treatment: £198, personal mouthguard free of charge, top-up opalescence kits can be bought in the UK for home use.
2. Veneers
3. Crowns or caps
What are they for?: Used to restore chipped or replace broken teeth.
How they work: An impression of the tooth is taken and the crown - made from metal or porcelain - is built in a laboratory to individual prescription, using a gold alloy covered with bonded porcelain. The old tooth is then cut down a millimetre or so to make room for the crown. The crown is then cemented on to the tooth.
How long does it take?: Two two hour appointments with a time gap of 5 days minimum.
How long does it last?: Permanent.
Cost: Crowns cost £171 each.
4. Bridges
What are they for?: To bridge a gap where a tooth is missing, or to close a gap.
How they work: A metal unit of three crowns is fashioned from porcelain. The bridge is then cemented to the teeth either side of the gap. These teeth are drilled down to attach the bridge either side of the gap.
The middle crown is solid to mimic a tooth, the other two are hollow in order to fit over the teeth. A colour is chosen to blend in with existing teeth and the shade of the bridge.
How long does it take?: Two one hour appointments with a time gap of 5 days minimum.
How long does it last?: From three years to fifteen years, if cleaned properly.
Cost: A 3-point bridge costs £513.
5. White fillings
What are they for?: For people with smaller gaps, chipped teeth or filling the edge of a tooth.
How they work: Made of a composite of resin and glass particles, they are cemented onto the existing tooth using a bonding agent.
How long does it take?: One appointment.
How long does it last?: They are rather less hard-wearing than veneers but should last for around 15 years if cleaned properly.
Cost £49 per tooth.
