Try gently massaging your gums. A gentle gum massage can help to ease pain and reduce inflammation by increasing blood circulation in the gums. Use a gentle, circular motion to massage the the swollen gums for about one minute. Remember to wash your hands before doing this and ensure that your fingernails are clean and clipped short.
Use anti-inflammatory drugs. Pain-killers and anti-inflammatory medication designed to reduce pain, can help soothe sensitive teeth. They work on reducing the swelling of the tooth nerves, which are agitated due to the chemicals from the whitening or bleaching agent used on the teeth. With reduction in the swollen area, the nerves stop tingling and pain gradually reduces. Please take any such medication only after consultation with your dentist.
