hello and welcome to hcm forum ks05218,
i would be glad to answer your query,
the dental history presented by you states that a
dental abscess is associated with your upper tooth, in order to confirm the tooth, we need to check your oral cavity clinically,
presence of an abscess causes pain, swelling and difficulty on chewing food.
i assume you have all these symptoms besides sore soft
palate, pain may also radiate to the temple,
therefore i would advise you to visit your
dentist,
he/she will rule out the cause and lay a treatment plan for you, do not delay your appointment as
tooth infection may spread to the surrounding tissues as well.
kindly avoid hot and spicy food, do not apply hot compresses over the swelling,
i hope i answered your query,
i wish you good health,
take care.
