Dentistry/Lasting ulcer


Hi there, I've had an ulcer in my mouth for around two weeks. Dentists always tell me i take really good care of my teeth and i can't remember the last time i got an ulcer.
Around the time i got it i had been eating sour candy which is what i thought brought it on, however it still hasn't healed. I'm scared because i am really crazy about taking good care of my teeth and was really surprised when i initially got it. With two weeks passed i am even more stressed about it!!
its on the side of my tongue and quite hard to see. i can only point it out when i feel around the area for the pain. i don't really notice i white head on the ulcer which is what i use to see when i got one.
I've been sick quite a few times in the last 2/3 months with an ear infection then ross river virus, tonsillitis and now a rash of some small red bumps on my arms and legs which i believe is from bacteria getting into a cut on my elbow.
I have been drinking small amounts of apple cider vinegar for the past 3 days to help with the rash and was wondering if that could be making the ulcer last longer?
Also Im 17 years old and before this year I rarely ever got sick (maybe a light cold once or twice a year).
I've been getting nervous about the sicknesses and now this ulcer has freaked me out!
Also, i never went to a doctor for the ear infection, is it possible that it may have caused the other problems?
Could the ulcer be a result of a weak immune system? because right now i can't figure any of it out and I'm stressed!
Thank you so much for your time!

Hi Caitlin and thanks for your question.

It sounds like you have had a few medical issues during the past few months which could have put some extra stress on your immune system, and the mouth is one area which presents with signs and symptoms of stress and reduced immune response, or in fact an increased immune response to infections elsewhere in the body. The best advice I could offer you, is to make an appointment with your dentist and get the ulcer checked out and diagnosed properly. There are numerous topical gels and mouth rinses that could be prescribed to you, in order to lessen the pain and facilitate healing. It will also give you some more peace of mind and allow you not to stress over this issue any longer, because this might be causing you undue worry itself which could be totally unnecessary. I hope this helps and wish you a speedy recovery from this ulcer, take care.

Kind regards
Dr Craig Peck

I am a General Dental Practitioner, with special interests in Cosmetic Dentistry & facial aesthetics and Periodontology, placing a strong emphasis on the establishment and maintenance of a healthy periodontium (the support structure of the tooth) before cosmetic options are considered. I uphold all principles of prevention above interventional treatment and try as far as possible, to remain conservative in my approach. I believe in detailed, open and honest patient discussion, establishing what the patients expectations are and what the reality is of achieving this and involving the patient at every level of the treatment. I have strong principles on ethical treatment and appropriate patient management. I have chosen to treat and rehabilitate many nervous and phobic patients, who, for whatever reason, find it impossible to take part in the very important task of even a routine check-up. I will accept questions relating to general and cosmetic dentistry (in conjunction with the use of facial cosmetic procedures) and dental fears/phobias. I will be more than willing to answer any academic questions in dentistry, biology, physiology, psychology and health sciences in general. As most dentists will tell you, there is often not only one way of dealing with a dental issue - so very often, there is no precise right and wrong way of approaching the problem. All clinicians vary when it comes to treatments and what works best in their hands is often the treatment that is advised. Be understanding of this and bear in mind that nothing lasts forever! Patients are happy to accept only a one-years warrantee when buying a new car, but seem to expect that dental work is going to last them their lifetime.


I have worked for many years in the UK and RSA as a general dental practitioner - within the NHS, private practice and the government dental health services. I am certificated for the administration of Botox and Dermal Fillers for facial lines and wrinkles as I have attended further courses in minimally invasive facial cosmetic procedures. I started seeing an increasing number of patients who presented with severe to moderate dental fears, even with full-blown phobias, so I started with the slow and patient task of tackling this problem and have successfully rehabilitated many patients. The key is good, effective, concise and understandable communication, shifting control from the dentist to the patient in order to slowly, but confidently, regain their trust back in dentistry, thereby giving them the feeling of achievement and this self-empowerment which drives them to the next level of treatment.
