Jaw and teeth pain can sometimes occur as a side effect of cancer treatments, including Letrozole. Sensitivity to hot and cold foods, along with a lingering ache, is not uncommon. Regular dental check-ups are essential to rule out cavities or gum issues. Dental clinics such as Indental Castle Hill in New South Wales specialise in managing dental sensitivity and jaw discomfort, and more information can be found by visiting click here. They can assess whether this pain is treatment-related or due to another dental condition, and suggest appropriate care to ease discomfort. Gentle, desensitising toothpaste and avoiding very hot or cold foods in the meantime can also help reduce the ache.
