Introduction
A healthy smile takes more than brushing and flossing at home. Professional dental exams and cleanings are the cornerstone of preventive care: they remove the hardened plaque you cannot reach yourself and catch small problems while they are still small.
At Alta Loma Dental Care in Rancho Cucamonga, Dr. Lee and our hygiene team provide thorough, gentle care for every age. Whether you are due for your six-month checkup or it has been a few years since your last visit, we will meet you where you are—no lectures, just a clear picture of your oral health and a plan to keep it that way.
What to Expect During Your Dental Exam
Your comprehensive exam includes:
- Visual inspection: Checking each tooth for decay, cracks and wear
- Gum health assessment: Measuring the pockets around each tooth to detect early gum disease
- Oral cancer screening: Examining the soft tissues of your mouth, tongue and throat for any abnormalities
- Digital X-rays (when needed): Spotting cavities between teeth and problems below the gumline
- Bite analysis: Making sure your teeth come together properly
- A review of existing dental work: Checking fillings, crowns and other restorations for wear or leakage
- Discussion: Answering your questions and reviewing anything we found
The Cleaning Process

Our hygienists use gentle, modern techniques:
- Scaling: Ultrasonic scalers and hand instruments remove plaque and tartar above and below the gumline
- Polishing: A fine paste smooths tooth surfaces, removes surface stains and makes it harder for new plaque to stick
- Flossing: A thorough clean between every tooth
- Fluoride treatment (optional, based on your needs): A quick varnish or gel that strengthens enamel—see our guide to professional fluoride treatment
A routine cleaning takes about 30–45 minutes, plus 15–20 minutes for the exam with Dr. Lee.
Why Every Six Months?
Twice-yearly visits are the standard recommendation for a reason. Here is what regular cleanings do that home care alone cannot:
- Remove tartar. Even with excellent brushing and flossing, some plaque hardens into tartar (calculus) within days. Once it does, it bonds to enamel and can only be removed with professional instruments. Our guide on removing tartar explains why home remedies fall short.
- Prevent cavities and gum disease. Clearing plaque and tartar removes the bacteria that cause decay and inflame gums—stopping gingivitis before it becomes periodontitis.
- Catch problems early. Cavities, early gum disease and oral cancer usually have no symptoms at first. Finding them at a routine visit means simpler, less expensive treatment.
- Freshen breath and brighten your smile. Removing odor-causing bacteria and polishing away surface stains leaves your teeth cleaner and noticeably brighter.
- Protect existing dental work. We check fillings, crowns and bridges at every visit so worn or leaking restorations are repaired before they fail.
- Get advice that fits you. Your hygienist will tailor tips to your mouth—brushing technique, the right electric toothbrush and toothpaste, or a daily oral hygiene routine that actually sticks.
- Save money over time. Preventive visits cost far less than the fillings, root canals or gum treatment that neglected problems eventually require.
- Make each visit easier. The more regularly you come in, the less buildup there is to remove—so appointments are shorter and more comfortable.
How Often Should You Come In?
Most patients do well with an exam and cleaning every six months. We may recommend visits every three to four months if you:
- Have gum disease or a history of it
- Have diabetes, or smoke or use tobacco
- Are pregnant (hormonal changes make gums more prone to inflammation)
- Wear braces or aligners, or have many restorations
- Build tartar quickly or get frequent cavities
Children should start visits early so we can monitor developing teeth and apply sealants or fluoride when helpful. At your first visit we will assess your risk factors and suggest a schedule that fits you.
Regular Cleaning vs. Deep Cleaning
A regular cleaning (prophylaxis) removes plaque and tartar above the gumline and is right for patients with healthy gums. If your exam shows deeper pockets, bleeding or bone loss, we may recommend a deep cleaning—scaling and root planing—that cleans below the gumline to treat gum disease. Deep cleanings are done with local anesthetic and may take more than one visit. Learn more on our gum disease treatment page.
Cost and Insurance
Most dental insurance plans cover preventive exams and cleanings at or near 100 percent, typically twice a year, with X-rays covered at 80–100 percent depending on frequency. Without insurance, a routine cleaning typically costs $75–$200, and a deep cleaning $200–$400 per quadrant. These are typical ranges; your written estimate depends on the exam, X-rays and your insurance. We verify your benefits before your appointment, file claims for you and explain any out-of-pocket costs upfront.
Tips for Between Visits

Make the most of your cleaning at home:
- Brush twice a day for two minutes with fluoride toothpaste
- Floss (or use a water flosser) once a day
- Limit sugary and acidic snacks and drinks, and rinse with water after them
- Use an antimicrobial mouthwash if we recommend one
- Replace your toothbrush or brush head every three to four months
