Teeth whitening trays- is it effective?
Teeth whitening trays are small trays that fit smoothly inside your mouth. They are made of rubber material or soft plastics and can be purchased either pre made or custom made. Mouth trays are like a mouth piece which holds the bleaching agents or gels. Bleaching gels are placed in the trays and then it is placed inside the mouth. The gel when applied in the tray tends to stay longer on the teeth than when it is applied on the teeth. The tray with the bleaching agent is allowed to stay inside the mouth for an hour and sometimes overnight for best whitening of the teeth.
The mouth tray prevents the whitening agents from getting in touch with the cheeks and gums. This protects the patient from any discomfort and sensations which usually happens with normal teeth whitening agents.
Teeth whitening can cause sensitivity of the teeth and the gums. Therefore, it is important that you select a brand that contains the required concentration of hydrogen peroxide. High concentration of hydrogen peroxide is harmful to the gums. Instead of having whiter teeth, you may end up in sensitivity. Hence, tray should be kept only for a short time and this should be able to give you whiter teeth. If the trays are kept for longer time, it can cause sensitivity, irritation and soreness of the gums and teeth.
