Thanks for your response and patience.Our mouth is a mirror of health or disease,sentinel or early warning symptom.Any unusual growth or symptom that you notice in your mouth should not be left unattended.
This hard knot which you see can be anything from a benign soft tissue growth to a bony growth.These conditions though rare but are present sometimes.This hard knot/lump can be anything from a benign soft tissue to bone growth,can also arise from teeth,It can be an osteoma,fibroma,a tori,an exostoses,fistula
or any cyst or a just a bone growth occuring due to some irritation in the oral cavity
Taking it in a positive way that it is painless so far and you donot feel thats its related to the underlying teeth as theres no pus,no infection
etc,you donot feel any pain
now but as you do feel pressure,it can be impinging on teeth beneath it and thus it also can be something asymptomatic in the beginning as it has been there only since two weeks,it might grow in due course of time causing other symptoms and pain.
Have it looked to be sure at your next appointment,if you donot see a dentist regularly,treat yourself and go.Peace of mind will be worth the fee alone.Get yourself properly diagnosed,get an xray done for the teeth underlying the knot/lump.Your dentist can guide you in a better way after actually visualizing it.
Such growths if required,can be removed easily by Surgical Excision which can be done by an oral surgeon in his office in single sitting.
