What problems can home whitening cause for teeth and gums?
The main problems are temporary sensitivity, gum irritation, uneven color, and worsening discomfort when teeth have decay, cracks, exposed roots, or poorly fitting trays.
What should you do before starting home whitening?
Have visible cavities, gum disease, restorations, and sensitivity assessed before whitening; use a product exactly as directed and keep gel away from the gums.
When should you stop home whitening and seek advice?
Stop and seek dental advice for severe or persistent pain, white or burned gum patches, swelling, or a result that becomes patchy after treatment.
What should you ask about a suitable home whitening plan?
Ask which ingredient and concentration suit your teeth, how restorations will appear afterward, and whether custom trays or another option is appropriate.
