Hello & welcome,
Actually giving advise on your condition without clinical examination is difficult as symptoms mentioned are not very clear. Still, i will put the best out from whatever you mentioned.
First, if you are having pain in lower teeth ,there might be caries associated with a single or multiple teeth which should be diagnosed soon.
Visit your
dentist to evaluate your oral cavity clinically. Check whether there is an impacted or partially erupted third molar on lower right side of the jaw.
This is because, third molars which are partially erupted or which are fully impacted may present with such painful symptoms especially when these molars are inclined mesially or horizontally.
Such horizontally or mesially impacted third molars put heavy pressure on the front tooth which then transmits the force to all the teeth present mesial to it.
Partially erupted molars usually have a flap of mucosa covering them underneath which food tends to accumulates thereby infection the area. This presents with soreness in the oral cavity specially on the affected side.
Soreness below jaw bone may be due to infection being drained in associated sbmandibular or sublingual
lymph nodes.
Pain on eating may be associated with periodontal fibers of the teeth being traumatized due infection or biting any hard objects.
Visit your dentist, get x-ray done to confirm the diagnosis. Keep your oral cavity clean always to avoid accumulation of the
plaque & food debris which may aggravate the situation.
Use of antibiotics or any other drugs will be decided by your dentist only after thorough examination.
Take care.
