Whitening


The reason why teeth get darker in colour is the accumulation of agents of different nature in them - pigments, organic molecules, antibiotics of the tetracycline group, coffee, tobacco, soft drinks, tea, red wine, dyes, etc. When roots of the teeth are treated this may lead to their change of colour to reddish-brown, sometimes almost black. There is a huge difference between teeth whitening and plaque and tartar cleaning (removing). Cleaning teeth with ultrasound and soda (airflow) precedes any whitening as by cleaning the plaque and tartar from the tooth surface we let the whitening agent reach the pigments accumulated in the deeper layers of enamel. There are three main types of whitening. These are:

1. Dental surgery whitening (whitening in the office). The dentist uses 30-35% carbamide peroxide gel. After covering the gums with light-curing composite, the whitening gel is applied and is activated by light. After the whitening, the whitening gel is washed or removed using the extractor. The procedure may be repeated at once, but not more than 3-4 times. The effect is noticeable immediately after the procedure, which lasts no more than 1 to 1.5 hours. The whitening effect lasts around 2-3 years.

2. Home whitening - It uses carbamide peroxide gel with concentration of 15 to 20 percent. It is necessary to have mouth trays made for your teeth. Squeeze gel into both upper and lower mouth trays and then pop them into your mouth. Leave them there for 4-6-8 hours, this can happen during sleep. The procedure is performed every day for 14-16 days. The whitening effect is achieved gradually every day; it is visible after 5-6 days. If necessary, you can continue whitening a few more days in order to achieve a better result. It necessary to visit the dentist monitoring the whitening to avoid possible complications of gums (as they are in contact with the gel for a long time), and to measure effect of bleaching on the scale of VITA. The effect lasts around two-three years.

3. Whitening of teeth after root canal treatment: it is necessary to clean the filling paste, which has led to colouring of the tooth and put in a whitening gel activated by light until the desired whitening. Once the desired whitening is achieved, a tooth filling is made.

If whitening is done by the manufacturer’s instructions and following the exact procedure, there are no negative effects. Sometimes hypersensitivity of the teeth appears which lasts from one to several days. Treating whitened teeth with gel containing fluoride helps to prevent or minimize the occurrence of such complications.
