Yes, it does but you need to look at the concentration of either carbamide peroxide or hydrogen peroxide in the products you are using, as over the counter products have legally less concentration in them than the product that we at Molloy dental can provide, therefore the procedure might sound the same but the outcome will be much better from us.
Other reasons why results from whitening might differ are influenced by many factors, such as previous trauma to your teeth, exposure to certain medications when the teeth were forming as a child, drinking tea or coffee, smoking, and the natural aging process. Not all teeth respond equally well to whitening.
In general, whitening is more successful on lighter (yellow) coloured teeth than on darker (grey/brown) coloured teeth; and whitening will not lighten existing dental restorations, such as tooth-coloured fillings, veneers, crowns or bridges.
Before whitening, it is important to consider how much of your existing dental work might have to be replaced following the treatment in order to achieve the desired results.
Obviously at Molloy Dental we just want you to get the best result so we will advise you as to whether you are suitable or not and we can determine if you are going to be a good candidate for whitening, it is better to know before rather than after.
