What is an oral and maxillofacial pathologist? 

We are specialized healthcare professionals who play a crucial role in diagnosing and managing diseases and conditions that affect the mouth, jaws, and related structures. Think of us as "detectives" of the oral health world.

Why you might see an oral and maxillofacial pathologist:
  • If you're experiencing persistent oral symptoms, such as unexplained pain, sores, or changes in the appearance of your mouth or face.
  • If you've been referred by your dentist or another healthcare professional for further evaluation and diagnosis.
  • If you're concerned about the possibility of oral cancer or other serious oral conditions.
What we at CCPS can do for you:
  • Oral Cancer Screenings: Early detection is key to successfully treating oral cancers. We offer comprehensive oral cancer screenings to identify potential risks and provide guidance on preventive measures.
  • Biopsies and Diagnostic Testing: Our experienced pathologists specialize in both performing and interpreting biopsies as well as diagnostic tests to determine the nature of lesions and abnormalities, ensuring prompt and accurate diagnoses.
  • Treatment Planning: Our team collaborates to develop tailored treatment plans that may include medical management, surgical intervention, or a combination of both, to address your oral health concerns effectively.
  • Patient Education: We believe in empowering our patients with knowledge about their conditions and treatment options. We take the time to explain diagnoses and answer all your questions to help you make informed decisions about your care.
  • Follow-Up and Support: Your journey towards optimal oral health doesn't end with treatment. We provide ongoing support and follow-up care to monitor your progress and ensure the best possible outcomes.
Some of the conditions we evaluate and manage:
  • Oral ulcers, including aphthous ulcers (canker sores)
  • Autoimmune conditions, i.e. lichen planus, mucous membrane pemphigoid, and others
  • Burning mouth syndrome
  • Xerostomia (dry mouth)
  • Candidiasis (thrush)
  • Oral manifestations of systemic diseases, including Crohn’s disease
  • Oral cancer
  • Salivary gland disorders and tumors
  • Allergic and hypersensitivity reactions
  • Oral premalignant lesions, including leukoplakia (white lesions)
