Hello,
I can understand your concern. Tooth decay is never associated with weight changes and
lightheadedness. Tooth decay can be associated with food
impaction in the tooth, sensitivity to hot and cold food, pain during chewing, at night or all the time and
referred pain can be felt in ear or temple.
Other than these, other symptoms are not associated with the decayed tooth and should be checked by a physician for other diagnosis related to hormonal system and blood pressure.
I would recommend to consult a physician before tooth extraction as lightheadedness due to blood pressure changes can cause complications during extraction and hormonal issues such as thyroid and diabetes should also be cleared or kept under control with medications, if present, before extraction. If the tooth causes pain by the time other issues are solved, you can take
Ibuprofen 400 mg or
Ketorolac 10 mg up to thrice a day for pain relief. Do not do heat compressions or hot/warm water gargles.
I hope this information helps you. Thank you for choosing HealthcareMagic. I wish you feel better soon.
Best,
Dr. Viraj Shah
