Please tell me can a tooth infection cause red bumps on the side of tongue.sore throat.hard bump inside the tongue.are these symptoms? maybe spreaded?

Hard to say: Bumps may be inflamed salivary glands.

Tooth Infection: Dental infections can spread... not sure if the tongue swelling is related or not. Swellings under the tongue can be quite dangerous since they push the base of your tongue into your airway. You need to be seen and treated ASAP.

Would be unusual: You may have two separate and distinct yet concurrent problems. Infected tooth mandates immediate treatment. Swelling inside tongue is worrisome. Red bumps can indicate lesion. Please see your Dentist or an Oral Surgeon without delay.
