1. Make sure your teeth are free from plaque and calculus (hardened plaque). Dr.Lazaris recommends doing the whitening treatment after having your teeth thoroughly cleaned so the whitening gel can actually absorb into the tooth structure.
2.For the love of peroxide, store your whitening products out of direct sunlight and warmth or else they can lose their potency.
3. Follow the instructions. “Whitening efficiency depends on contact time with the teeth so you can’t rush it,” urges Dr. Lazaris. However, if you’re experiencing pain or sensitivity, give your mouth a good rinse with tepid water and give it a break for a few days. If the pain continues, seek out professional advice.
4. After your at-home teeth whitening treatment, follow up with a whitening toothpaste. “I see a big difference when I’ve whitened my teeth and use Colgate Advanced Whitening + Tartar Control – the one in the gold packet,” says one Gritty Pretty staffer. If you’re experiencing sensitivity post-whitening, also try: Sensodyne Gentle Whitening Toothpaste.
