There’s no denying the science of tooth bleaching – though it is completely safe, it can cause sensitivity and patients need to know that there are solutions you can offer. pola soothe – a desensitising gel that can be applied before and after treatment – is one such example, containing sustained-release potassium nitrate, which blocks the pain, and fluoride, which further remineralises the teeth. Best of all, pola soothe does not interfere with the whitening process, so patients can feel reassured that their results won’t be compromised by sensitivity issues.
