Hi and welcome to HCM,
Dark shadow or areas seen in the x ray films is called radiolucent areas . Any pathology associated with the tooth can appear radiolucent . It can be a cyst , periodontal abscess , periapical granuloma , necrotic areas , bening tumours or it may be malignancy.
You dint mention the other symptoms , like pain and mobility in the tooth . Exact diagnosis can be made by clinical examination and related x rays , i suggest you to get an OPG radiograpg done that shows the exact relation of the pathology with adjacent teeth , jaws and other vital structures.
Approach an oral surgeon who can do appropriate diagnosis and treatment.
take care.

Hi,
Thank you for the query.
X-ray of the teeth or bone will show presence of any infection or tumor or growth . Cancer cannot be detected by just taking an x-ray . Any malignancy can be diagnosed based on the signs and symptoms and biopsy of the tissue . It could be a beningn growth or just a periapical cyst.
You have not described about any signs and symptoms to comment on the condition .
I would advise you to see your dentist and discuss about the situation to rule out the excisting problem.
Hope this information helps you.

Hi,
Welcome to the forum.
Soft objects appear black and called as radiolucent.
What you see as grey/black on x-ray:
Decay.
Abscess.
Nerves and blood vessels (the pulp).
Gum in the spaces between teeth.
I would suggest getting this evaluated by an oral surgeon for an accurate diagnosis and appropriate management.
I hope this is helpful to you.
Regards.

Dear fried

Thanks for sharing your concern.

What made you think that it is a cancer? Dont be worried at all.

For detecting cancer an its type biopsy is done not an x ray. Your dentist must be needing a bigger x ray like OPG for that he could have asked your son to visit hospital.

In x ray you can see hard and soft tissues like teeth, bone, cyst, periodontal abscess , periapical granuloma , necrotic areas , bening tumours or quite rarely it may be malignancy too .

Dark shadow or areas seen in the x ray films is called radiolucent areas . Any pathology associated with the tooth can appear radiolucent .

You have not mentioned the other symptoms, like pain and mobility in the tooth. Any associated bleeding?

Exact diagnosis can be made by clinical examination and related x rays.

i suggest you to get an OPG radiograph done that shows the exact relation of the pathology with adjacent teeth , jaws and other vital structures.

thanks

Hello and thank you for your question.
