Chipped tooth repair?

[Erik]

I have a chipped tooth (Lower left 30) otherwise I have good dental health. The chip is at the inner gum line where the enamel of the crown meets the root. Other than being able to feel the chip with my tongue/finger it causes me zero discomfort. I have been advised that it is fine and to keep brushing it. Knowing nothing about dentistry my self I do not know the proper course to correct this before it becomes a bad issue for my tooth. So I have a few questions;
1, Is it ok to just let it go with normal dental care and this will not jeopardize the tooth?
2, Is this something that can be repaired to protect the tooth?
2a, If its repairable just what can be done?

I attached 2 probe pictures. The chipped area has not changed in approximately 6 months. It does not bleed but the coloration is yet another concern for me.

Any advice is greatly appreciated.

The area can definitely be fixed with a dental filling. Did the dentist take an x-ray to rule out any decay that might be the reason for the chip?

 

[Erik]

Yes. Full x-ray set was done. No decay detected anywhere. What makes me wonder is why both the hygienist and the dentist would suggest leaving it alone. Would the filling just be for appearance or would it protect the tooth?

 

[Dr M]

The filling in that area is sometimes technically difficult, due to being close to the gum line. Exposed dentine like that might later on lead to cold sensitivity and a filling might help to cover the exposed dentine. If there is no decay detected however, and you are not experiencing any cold sensitivity, you can only monitor it for now.

Thank you very much for your response. Having limited knowledge in dentistry it just seemed odd to not cover an area on the tooth that was not naturally exposed. I just didn't want to risk an otherwise healthy tooth. I understand your answer and truly appreciate your time.
