Tooth Whitening Portishead
There are two main types of tooth whitening available:
Professional home whitening kits
Professional home whitening kits involve the dentist taking an impression of your teeth and getting the technician at the dental laboratory to construct custom tooth whitening trays. These are worn for about two hours a day or overnight and contain a professional tooth whitening gel supplied by the dentist. These are worn until you are happy with the results which usually take between 2 to 6 weeks depending on the individual circumstances. This method of tooth whitening produces great long term results, with less chance of sensitivity and with the opportunity to “top up” the effect in future years by purchasing the correct whitening agent. This has long term cost effectiveness and you have more control over the final shade that is gently achieved and with a neutral ph buffered product.
Laser tooth whitening
Laser tooth whitening takes place at the dental surgery and uses a light activated bleaching gel to whiten your teeth. The bleaching agent contains a high percentage of peroxide and so the gums and lips are isolated and protected. The gel is applied to the teeth and the light is applied. This typically takes about an hour and the teeth can lighten several shades. In our experience with this treatment there can be quite a degree of sensitivity and it can last for longer. The effects are instant partly due to the drying out of the enamel and this can be seen as a less subtle change. If further whitening is desired then the process can be done again or continued with a home bleaching kit as outlined above (at additional cost).
Presently, we recommend the professional home whitening kits as they offer greater flexibility in terms of colour control, cost effectiveness and the ability to top up the effect in the future.
The law was changed on the 31st October 2012 regarding tooth whitening meaning it is illegal for any person to whiten teeth if they are not a dental professional. Health and beauty clinics are not legally permitted to carry out tooth whitening. There was also a restriction introduced on the concentration of bleaching agents that could be used, and a restriction on age of the patient so that it is not permitted to be done on anyone under the age of 18.
We pride ourselves on using professional whitening products that do not damage the tooth structure and minimise sensitivity. Every bleaching treatment poses different challenges. We will discuss with you, and provide an individual and appropriate
