If you are not in a habit of brushing your teeth on a regular basis then you will want to start this a few weeks before you want to whiten your teeth. Be sure you brush your teeth using a soft toothbrush.
Kui sul pole senimaani olnud harjumust oma hambaid regulaarselt pesta, siis muuda see endale harjumuseks vähemalt paar nädalat enne kui soovid oma hambaid valgendama hakata.
