I saw my dentist 2-3 weeks ago, would they have noticed if i had oral cancer? i don't show signs/symptoms but my cheeks tend to peel

Would have noticed: Oral cancer is exceedingly rare at your age and would not cause peeling of the cheeks. And for sure your dentist would have noticed if you had oral cancer. Why is it even on your mind? Are you worried about HPV? Even that causes throat cancer, not mouth; also is rare, despite recent media publicity about it; and almost never causes cancer before age 40-50.

Next visit: It is very unlikely that you have oral cancer. It is not safe to assume that dentist would have noted oral cancer, as it may be beyond the usually visible mucosa. There is no urgency, but at your next visit you should request your dentist or your doctor for an assessment for oral cancer. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. Get HPV vaccine.

I hope so: Dentists are trained to examine patients for signs of oral cancer. A white patch for more than two weeks, a lump or an open sore that won't heal should all be checked. For your cheeks if you are not sunburned or using meds on your skin ask your dermatologist to check it out. Sounds like you're fine.

Of course: Cancer screening protocols: a thorough oral, head and neck cancer examination performed at each recall dental appointment. No exceptions. This is a standard of dental care in USA.

Contact DDS: If you have any concerns, return back to the dentist, ask for a referral to an oral surgeon or contact your primary care MD.

Oral cancer: Oral cancer examination protocols are followed at each Dental examination. If you are not a smoker, do not consume alcohol in excess, at your age Oral cancer is rare. What's peeling? If the outside of your cheeks see a Dermatologist. If the inside, see an Oral Surgeon. And take a list with you of all Meds, supplements, and vitamins.

Could be our toothpa: We have several patients that are sensitive to a particular ingredient in some big name toothpastes.
