Final answer:
Jason should consult a dentist if he experiences persistent oral health symptoms such as dry mouth, sore throat, chapped lips, oral thrush, or mumps, as well as any other unresolving or worsening mouth-related issues.
Step-by-step explanation:
When considering whether to consult a dentist, Jason should be aware of various symptoms that align with oral health issues. While dry mouth, sore throat, and chapped lips can be related to general health conditions, they can also indicate dental concerns such as dehydration affecting oral health, gum disease, or other oral infections.
Other symptoms that might warrant a dental visit include cracks in the corners of the mouth (cheliosis), inflammation and redness of the tongue, and signs of oral infections such as oral thrush or mumps. Persistent symptoms like these, especially when not resolving or worsening, should prompt Jason to seek professional advice from a dentist or physician.
