Hello and thank you for your question.
You may have a torus palantinus. This is an outgrown of bone found in the hard palate along the midline and a common benign finding. You may have had this for a while but did not take notice until after the procedure. If it is near the gum line, and you had a rubber dam placed, this could be a spot of trauma from the dental clamp and is part of the healing process.

Keep an eye on the spot. If it is non-ulcerated and flesh colored it can wait two weeks. This is most likely benign and you can rest easily. Please bring this up with your dentist to evaluate so he may bury any more anxiety or fears you may have.

Best wishes and good health.

Hi, the lump might be a hemangioma, which is the collection of blood at one spot which occurs due to injury to the blood vessels, there is nothing to worry about its a benign condition and often regresses on its own. When you visit your dentist after 2 weeks and if the lesion still does not regress then perhaps a biopsy/ consultation with oral medicine specialist will help.
Take care

HELLO AND WELCOME,
the lump may be due to many reasons.
your filled may be decayed and involved periapical area also.
get an x-ray of the tooth to rule out any underlying pathoses.if there is periapical infection and abscess,then remove the filling.extirpate entire infected pulp.abscess can be drained and curetted.
obturation of canal should be done only after removing vital pulp completely.
deep scaling has to be done to remove gingivitis.
complete course of antibiotics should be taken.
novacaine injection can also cause hard lump if there was abscess already.
this is due to occurence of antibioma.
crown has to be placed only when the hard lump subsides.

i do agree with dr. geoffrey, however would like to know whether it was present long before or during the course of this treatment.
if its bony hard then its torus palatinus however what i feel is that if it has emerged lately it could be due to the infection caused due to upper molar tooth whose palatl root is quite long and whose infection reflects on the palte i:e the roof of the mouth
in that case the tooth needs to be done root canal treated again.

Hi,

Thanks for asking the query,

Hard lump on the roof of the mouth can be a TORUS PLATINUS, it is bony outgrowth in the midline of the palate which is beningn in nature

Or it can be ulceration due to physical trauma or allergy caused by chemicals at the time of filling the tooth.

Other than this it can be due to infected tooth draining its abscess in the palatal bone.
A thorough clinical examination by the concerned Dentist is required.
Take an OPG radiograph to determine the diagnosis nad plan appropriate treatment.

Hope this helps out.

Regards...
