Preventative action is paramount for helping to keep teeth white. Avoiding highly coloured foods and drinks where possible is a good idea as they can increase teeth staining. In terms of toothpaste, there are whitening toothpastes that are specifically designed for discoloured teeth. They work by being slightly more abrasive than your regular toothpaste so they can help remove stains better, but it’s worth noting that they don’t actually whiten the teeth. I’d also avoid
teeth whitening kits bought over the counter as the concentration of the whitening gel that can be sold is very low so they won’t really have an effect. It’s for this reason that I’d always recommend going to your dentist for whitening kits as we can offer the highest strength and quality.
