Deep teeth cleaning is a common procedure recommended by dentists to help control or prevent gum disease. Millions of people receive deep cleanings every year because regular brushing, flossing, and professional dental cleanings sometimes can’t fully eliminate tartar and plaque buildup beneath the gum line. Left untreated, this buildup can cause gum inflammation and infections. Over time this can potentially lead to severe oral health problems, including tooth loss and damage to the jawbone. If your dentist has recommended a deep cleaning, you probably have some questions, particularly about how long it takes.
How Long Does a Deep Teeth Cleaning Usually Last?
Typically, a deep cleaning session will last anywhere between one to two hours. However, this can change based on your specific oral health needs. Dentists often perform deep cleanings by dividing your mouth into quadrants. Depending on the severity of plaque and tartar, each quadrant usually takes around 30 to 45 minutes to clean thoroughly.
Why are Deep Teeth Cleanings Are Sometimes Divided?
Dentists often recommend splitting deep cleanings into more than one appointment. This is especially common when all four quadrants of the mouth require treatment. One reason dentists divide the process is to make the procedure more comfortable for patients. Because deep cleanings usually require numbing with local anesthesia, treating the entire mouth at once would mean numbing all areas, making it challenging to speak or eat comfortably afterward. Splitting the procedure into separate visits allows half of your mouth to heal while you can comfortably use the untreated half for eating and speaking.
Another reason for multiple sessions is comfort. Deep cleaning can leave your gums sensitive or sore for a day or two afterward. By scheduling separate visits, you can recover and feel less discomfort overall before starting the next half. This approach also provides your dentist with a clearer focus during each session, helping ensure a thorough and effective cleaning.
Factors That Influence How Long a Deep Cleaning Takes
The length of your deep cleaning can vary based on several factors. One major factor is the amount of buildup present under the gum line. If you have significant plaque or tartar, it will naturally take more time to clean effectively.
Another factor is how many quadrants require treatment. Some patients might only need deep cleaning in one or two quadrants. This would significantly reduce the total treatment time. Others may need treatment in all four quadrants, requiring longer or multiple appointments.
Your comfort level and sensitivity also play a role in how long it takes. If you experience discomfort or sensitivity during the procedure, the dentist may take extra measures like applying additional numbing agents, which can slightly extend your appointment time.
What’s Next?
If you're preparing for a deep cleaning, discuss your individual needs with your dentist. They can provide a clearer picture of what to expect during your procedure, including how long it might take, whether multiple visits will be needed, and what steps you should take to promote healing afterward.
