If he is going through severe pain that may be sign of gingivitis / tooth decay. Teeth whitening is cosmetic. You should take him to see a dentist.
By the age of 7, the first adult molars erupt, establishing the back bite. During this time, an orthodontist can evaluate front-to-back and side-to-side tooth relationships. For example, the presence of erupting incisors can indicate possible overbite, open bite, crowding or gummy smiles. Timely screening nips issues in the bud and helps maintain that incredible smile.
