　　Title: 《北上洗牙有冇年齡限制？》 — Is There an Age Limit for Going North for a Dental Clean?

　　If you’ve been hearing friends say they “go north” for a quick dental clean—usually to Shenzhen or other Mainland cities from Hong Kong—you might be wondering: is there any age limit? Can kids, teens, adults, and seniors all do it, same same? Short answer: no strict age limit. Professional teeth cleaning (scaling and polishing) is suitable for most people, from little ones to grandparents. The key is choosing the right technique, the right clinic, and timing that fits your health needs. Sabai sabai, but smart.

　　What “Dental Cleaning” Actually Means

　　A standard dental clean removes plaque and tartar with tools like ultrasonic scalers or manual hand instruments, followed by polishing. It helps prevent gum disease, bad breath, and cavities. Think of it as a deep refresh for your mouth—no drilling, usually no injections, and done within 30–60 minutes.

　　Kids and Teens: Start Early, Go Gentle

　　- Age range: Many dentists begin professional cleaning around age 3–5, depending on cooperation. For younger kids, it’s more about check-ups, brushing coaching, and fluoride.

　　- Technique: Gentle scaling (often manual) and soft polishing. If a child is anxious, clinics may go slow, keep it playful, or split visits—no need to force.

　　- Braces and aligners: Teens with orthodontic treatments benefit a lot from regular cleaning to avoid plaque build-up around brackets.

　　- Frequency: Every 6 months is common, but the dentist may suggest 3–4 months if there’s high plaque or early gum issues.

　　Adults: Routine Maintenance With Real Benefits

　　- Gum health: Scaling reduces inflammation and bleeding. If you smoke or love sweet drinks, plaque can be heavy—cleaning helps reset the mouth.

　　- Sensitivity: Mild sensitivity after cleaning is normal, especially if gums were inflamed. Using desensitizing toothpaste and avoiding ice-cold drinks right after can help.

　　- Pregnancy: Dental cleanings are safe and recommended—second trimester is most comfortable. Good gum care lowers gum bleeding and makes pregnancy more sabai.

　　- Frequency: Typically every 6 months. If you have gum disease (periodontitis), you may need more frequent maintenance.

　　Seniors: No Age Limit, Just Extra Care

　　- Recession and implants: Seniors often have gum recession, crowns, bridges, or implants. Cleaning is not only safe, it’s important to protect these investments.

　　- Dry mouth: Common with certain medications; leads to faster plaque build-up. More frequent cleans may be helpful.

　　- Pacemakers and devices: Most modern pacemakers are fine with ultrasonic scalers, but it’s good practice to inform the dentist. If there’s any concern, clinics can use manual scaling—same clean, less vibration.

　　- Medications: If you’re on blood thinners, cleaning is usually safe. Expect a bit more bleeding; the dentist will work gently. Always share your medication list.

　　Health Conditions That Need a Quick Chat First

　　- Heart conditions: People with certain high-risk heart issues (e.g., prosthetic heart valves, prior infective endocarditis) may need antibiotic prophylaxis for procedures that manipulate the gums. This is rare but important—bring your medical notes and ask.

　　- Active infecti

　　ons or severe pain: If you have swelling or fever, you might need a different treatment before cleaning. Don’t wait too long; see a dentist promptly.

　　- Pregnancy complications: Most expectant moms can proceed, but if your obstetrician advises caution, reschedule to a safer time.

　　Going North: What To Expect in Shenzhen or Other Mainland Clinics

　　- Costs: Often lower than Hong Kong—many people say “same same but cheaper.” But price depends on clinic quality, location, and add-ons (X-rays, fluoride, deep cleaning).

　　- Booking: Many clinics accept walk-ins and app bookings. Weekdays are less busy; weekends fill fast.

　　- Language: Larger clinics have Cantonese- and English-speaking staff. Confirm in advance to avoid miscommunication.

　　- Sterilization: Ask about infection control and instruments. A professional clinic will explain clearly—no worries.

　　- Records: Keep a copy of your bill and treatment notes. Handy for follow-up at home.

　　- Payments and insurance: Mainland clinics may accept WeChat Pay/Alipay and cards. Check whether your insurance covers cross-border dental care—sometimes it’s out-of-pocket.

　　- Travel: Bring ID documents and check any health/travel advisories. Easy trip is better than last-minute rush.

　　How Often Should You Clean?

　　- Standard: Every 6 months for most people.

　　- Higher risk: Every 3–4 months if you have gum disease, heavy plaque, braces, or dry mouth.

　　- Kids: Follow what your dentist suggests—usually aligned with check-ups and fluoride schedules.

　　Aftercare Tips for a Smooth, Sabai Experience

　　- Mild soreness or sensitivity can happen; it should settle within 24–48 hours.

　　- Avoid very spicy or very cold foods right after the clean if your gums feel tender.

　　- Brush gently, floss daily, and consider a mouthwash if the dentist recommends.

　　- If bleeding or pain persists after a couple of days, check back with the clinic.

　　FAQs, Quick and Clear
