Warning Signs of a Dental Clinic to Avoid
Excessive treatment plans: Be cautious of clinics that immediately recommend expensive implants or orthodontic treatment during the first visit. Avoid clinics that rush you to make decisions on the spot without sufficient examination and consultation.
Repeated complaints in reviews: Be careful if the same issues are mentioned repeatedly in reviews. In particular, if overtreatment, rudeness, or poor pain management are repeatedly mentioned, it is better to look elsewhere.
Poor explanations during consultation: Clinics are hard to trust if they provide insufficient explanations about treatment procedures or costs, or answer questions carelessly.
Facility and hygiene issues: Clinics with poor cleanliness or equipment management should be avoided due to infection risk.
