Dr. Fernanda Valdivia — English-Speaking Dentist in Condesa, Mexico City

Identify warning signs in your mouth

Have you had any of these symptoms for more than two weeks?

According to Mayo Clinic, any oral symptom that persists for more than two weeks should be evaluated by a dentist or specialist.

Color changes

Persistent patches (white, red or brown) or changes in the appearance of the papillae.

Swelling or growths

Firm growths on the cheeks, lips or any area of the oral cavity.

Chronic ulcers

An open sore that hasn't healed after two weeks, with no clear cause.

Suspected HPV / STIs

Warts or papillary lesions in the mouth, evaluated with complete confidentiality.

Oral Cancer Screening

Premalignant changes are highly treatable when caught early — a specialized screening turns early detection into peace of mind.

Burning or dry mouth

Burning or severe dryness can point to conditions like oral candidiasis or Sjögren's syndrome.

Frequently asked questions

What patients ask us most

Do you see international patients or tourists visiting Mexico City?

Yes. Dr. Fernanda conducts consultations in English, so no translator is needed. Many patients visiting Mexico City combine dental or oral care with their trip — the office is a short walk from the Nuevo León Metrobús stop in Condesa, and same-day and urgent appointments are available. Message us on WhatsApp with your travel dates and we'll do our best to fit your visit.

When should I be concerned about a mouth ulcer?

If a sore doesn't go away after 14 days with no clear cause — an accidental bite, friction — see a specialist. Common ulcers heal on their own within 1 to 2 weeks. When they persist, they may indicate an infection, an autoimmune condition, or a premalignant lesion that requires a formal diagnosis.

What is an oral biopsy, and does it hurt?

An oral biopsy is a procedure where a small tissue sample is taken under local anesthesia and sent to a lab for a definitive diagnosis. It doesn't hurt during the procedure, takes just a few minutes, and you can return to your normal day right after. Post-procedure discomfort is minimal and resolves within 1 to 3 days.

How long does it take to get oral biopsy results?

Between 5 and 10 business days, depending on the pathology lab. Once results arrive, Dr. Valdivia explains them in detail and designs the appropriate treatment plan. The full process — from sample collection to the results consultation — is completed in under two weeks.

What oral cancer warning signs should I watch for?

The most common signs include white or red patches that don't go away, ulcers that haven't healed after 14 days, lumps or growths on the lips, tongue, cheeks or palate, and numbness or difficulty swallowing. Oral cancer detected early has a 5-year survival rate above 80%; detected late, that rate drops sharply.

Can HPV appear in the mouth?

Yes. Human Papillomavirus (HPV) can appear in the oral cavity as papillomas, warts or flat lesions on the lips, tongue, palate or throat. Many cases are asymptomatic, but the lesions can be detected during a specialized exam. Some HPV subtypes are linked to oropharyngeal cancer.

What's the difference between a dentist and an oral pathologist?

A general dentist focuses on cavities, gums and restorations. An oral pathologist has specialized training to diagnose soft-tissue disease: mucosal lesions, autoimmune conditions, infections and potentially malignant lesions. Dr. Fernanda Valdivia combines both specialties in a single practice, so you don't need a separate referral. In Mexico, this profile is also known as an "estomatólogo" — a professional with a comprehensive view of the oral cavity that goes beyond the teeth.

Does chemotherapy or radiotherapy affect the mouth?

Yes. Cancer treatment targeting the head, neck or chest can cause mucositis (inflammation and ulcers in the mucosa), xerostomia (dry mouth from salivary gland damage), fungal infections and, in severe cases, osteoradionecrosis. Timely management of these side effects significantly improves quality of life during and after treatment.

What can cause persistent burning or dryness in the mouth?

Persistent burning or dryness in the oral mucosa has common but treatable causes. Oral candidiasis — a fungal infection — causes burning, whitish patches and a bad taste; it responds well to antifungal treatment. Sjögren's syndrome is an autoimmune disease that affects the salivary and tear glands, reducing saliva production. Both conditions require a specialized diagnosis to rule out other causes.

Do you offer same-day emergency appointments?

Yes. We reserve slots seven days a week for dental emergencies: acute pain, abscesses, broken teeth or any situation that can't wait. For urgent care, message us on WhatsApp and we'll give you the first available slot of the day.
