As we go through life, eating and drinking all sorts of highly pigmented foods and drinks, our teeth collect their traces. Fancy a glass or 2 or red wine to celebrate the end of dry January? Drinking loads of tea and coffee in the meantime? Perhaps you are a big fan of tomatoey sauces? Or maybe you are still a smoker? If you consume any or all of the above, as they pass by your teeth, they will be leaving tiny traces of themselves lodged in the pores of your tooth enamel.
That’s right, tooth enamel is porous, and when we eat or drink, it becomes more so, which is how it is able to collect traces of food and drink. Tooth brushing can’t dig around in those pores, and even the hygienist can’t get rid of surface staining if it’s down in the enamel. But teeth whitening can.
Teeth whitening gels use hydrogen peroxide to gently lift out these surface stains. If you have ever used hydrogen peroxide on an infection in your skin, you will know how it bubbles out the infection. It does something similar to surface stains on your teeth.
How quickly it works depends on the percentage of hydrogen peroxide in the whitening gel. The gel we use when we carry out power whitening treatments in the clinic here at The Scottish Centre for Excellence in Dentistry in Glasgow is stronger. The whitening gels you take home contain 10% hydrogen peroxide.
The stronger gel can remove 60-70% of your stains in just an hour when you come into the clinic. We protect your lips and gums with plastic barriers before painting on the gel, which is activated by a UV light.
If you still need further whitening after that, we can supply you with a take home kit. This kit has gel trays that are made to fit your teeth exactly from impressions made with dental putty. You put the gel in the trays and wear them for a short period each day, and it will take about 2 weeks to remove the staining.
Try whitening and watch the years fall away from your smile.
