What should I do about tooth sensitivity and swelling?

If tooth soreness and discomfort are caused by dental plaque, patients are advised to undergo teeth cleaning to remove plaque and tartar, thereby relieving the symptoms. If the discomfort is due to tooth decay, treatment for cavities is required, including filling the decayed areas to restore the tooth and alleviate the symptoms. If the soreness results from tooth sensitivity, patients are recommended to use specialized toothpaste or mouthwash to reduce sensitivity and thus ease the discomfort.
