什麼是洗牙

洗牙是指專業的牙齒清潔，利用超聲波或手動器械去除牙齒表面的牙石、牙菌斑及色素沉積，再進行拋光，使牙齒表面光滑，減少細菌附著。洗牙的主要目的不是美白，而是預防牙周病、牙齦炎及蛀牙，並保持口腔健康。

甚麼情況下要洗牙

  • Prevention of tartar, cavities and periodontal diseaseRegular 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.
  • Other oral phenomenaYou 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.
  • Special ethnic groupsCertain 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.

Oral examination

The dentist will conduct a comprehensive examination of the health of the teeth, gums, and oral mucosa to check for cavities, periodontal disease, or other abnormalities. They will also assess the distribution of tartar and plaque to determine the appropriate cleaning method. If necessary, the dentist may also recommend an X-ray (at an additional cost) to gain a deeper understanding of the tooth roots or the location of hidden lesions.

超聲波洗牙

Dentists use high-frequency vibration instruments to break up and remove tartar and plaque from the tooth surface and below the gum line. This method is particularly effective at cleaning deposits between teeth and deep in the gums, improving cleaning efficiency and reducing wear on the tooth surface.

手動清潔工具輔助

牙齒拋光

Dentists use polishing paste and soft tools to gently polish the tooth surface. This not only removes minor stains but also makes the tooth surface smoother, thereby reducing bacterial adhesion and plaque formation, which helps maintain oral hygiene and aesthetics.

Common problems with teeth cleaning

如有洗牙問題，可WhatsApp我們，會有牙醫親身回答

Will it hurt when I get my teeth cleaned?

Healthy gums usually do not feel pain; if you experience discomfort, it may be a sign of gingivitis or periodontal disease.

Will teeth cleaning damage my teeth?

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.

How often should I get my teeth cleaned?

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.

Is it easy to experience bleeding gums after a teeth cleaning?

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.

Does teeth whitening make teeth whiter?

Teeth cleaning can remove stains and make teeth appear whiter, but it does not have a whitening effect; a separate bleaching procedure is required.

How long does a teeth cleaning take?

A regular teeth cleaning takes about 15 to 30 minutes, while a deeper cleaning may take longer and require multiple sessions.


Does teeth cleaning make teeth looser and widen the gaps between teeth?

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.

Are your teeth sensitive after a teeth cleaning?

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.
