Preventing oral problems

Prevention of tartar, cavities and periodontal disease
Regular dental cleanings can effectively remove bacteria and plaque from the tooth surface, eliminate tartar, prevent its further development, and reduce the risk of cavities, gingivitis, periodontitis, and other oral problems.
Special ethnic groups
Certain groups are advised to have their teeth cleaned every three months, including pregnant women, diabetics, those with periodontal disease, braces wearers, people with dry mouth or taking high blood pressure medication, and patients undergoing chemotherapy or radiation therapy. These groups are more prone to plaque buildup, gingivitis, or weakened immunity, and therefore need regular cleanings to prevent periodontal disease and other oral diseases.
Other oral phenomena
You should schedule a professional dental cleaning immediately if you experience any of the following: red and swollen gums, bleeding gums while brushing, or persistent bad breath – these could be early signs of periodontal disease; noticeable tartar or staining on the teeth indicates incomplete cleaning; feeling unclean even after daily brushing may indicate excessive plaque buildup; and those with a history of cavities or periodontal disease should have regular dental cleanings to prevent recurrence. These conditions suggest that your oral health may be compromised and should not be delayed.

Teeth cleaning at Qi Ren Dental Center typically involves the following steps:
Common problems with teeth cleaning
Healthy gums usually do not feel pain; if you experience discomfort, it may be a sign of gingivitis or periodontal disease.
Teeth cleaning can remove stains and make teeth appear whiter, but it does not have a whitening effect; a separate bleaching procedure is required.
Teeth cleaning uses ultrasonic vibrations, which will not damage the enamel. Widening of the gaps between teeth is a normal phenomenon after tartar is removed.
A regular teeth cleaning takes about 15 to 30 minutes, while a deeper cleaning may take longer and require multiple sessions.
It is recommended to have your teeth cleaned every six months to a year. If you have periodontal disease, you may need to have your teeth cleaned every three to four months.
Under normal circumstances, teeth cleaning does not cause teeth to become looser or gaps to widen. However, some patients already have severe periodontal disease, leading to gum recession and loose teeth. When they undergo teeth cleaning, the tartar that previously filled the gaps and supported the teeth is removed, causing the teeth to become loose again, which is then mistakenly attributed to the cleaning itself. On the contrary, regular teeth cleaning helps to thoroughly clean teeth and prevent the worsening of periodontal disease and gum recession.
Mild gum bleeding after a dental cleaning is common, especially for those who don't get their teeth cleaned regularly or have poor oral hygiene. During a cleaning, the dentist removes plaque and tartar from the gum line, which can irritate already inflamed gums and cause bleeding. However, this is usually temporary and will decrease with improved oral health and regular cleanings. If the bleeding persists or becomes very severe, it's advisable to consult a dentist as soon as possible to rule out other underlying oral health problems. Regular cleanings help maintain healthy gums and ultimately reduce the risk of bleeding.
Teeth may become sensitive and sore after a dental cleaning, likely due to the removal of tartar and exposure of the tooth roots. This sensitivity is usually temporary; the teeth will gradually adapt over time, and the sensation will lessen. It is recommended to avoid extreme temperatures and high-sugar foods for 1-2 weeks after a cleaning, and to maintain good oral hygiene to help the teeth adjust and reduce sensitivity.
For patients with existing periodontal disease and receding gums, if sensitivity after a cleaning persists for an extended period or is accompanied by other discomfort, it is recommended to consult a dentist promptly to ensure there are no underlying problems. To alleviate post-cleaning sensitivity, the dentist may recommend using a specialized toothpaste for sensitive teeth and maintaining good oral hygiene habits.
