Everybody wants bright white teeth!
Tooth whitening removes staining and lightens the colour of the teeth. Current evidence suggests that the effect lasts eighteen months and that there is no harmful effect to the teeth and gums. The current evidence confirms that the procedure is successful in 92% of cases.
Tooth whitening can be completed in the dental surgery (power bleaching or laser bleaching) and in the patient's home (at-home whitening or tray bleaching) or just at home and there is no doubt that lighter teeth impart a pleasing and youthful appearance. With both methods the end result is the same but power whitening achieves 60 to 70% of the final result within 60 to 90 minutes and means there is less for the patient to cope with at home.
At home tooth whitening is completed with close fitting mouth guards which are loaded with 10% hydrogen peroxide and worn for 30 to 60 minutes per day. The normal course lasts ten to fourteen days or five to seven days if power whitening has been completed.
