A deep cleaning, formally known as scaling and root planing, is a specialized non-surgical procedure designed to treat periodontal disease below the gumline. This treatment involves removing built-up plaque, tartar, and bacteria from the tooth roots and smoothing the root surfaces to encourage the gum tissue to reattach. Since this process addresses infection beneath the surface, it is more intensive than a regular cleaning and often requires local anesthesia. Proper aftercare, particularly concerning dietary choices and timing, is important for successful healing and minimizing post-procedure sensitivity and discomfort.
The Recommended Waiting Period
The most important factor determining when you can eat is the presence and dissipation of local anesthesia. Dentists recommend waiting until the numbness has completely worn off before attempting to chew or swallow food. Eating while the mouth is numb significantly increases the risk of accidentally biting the cheek, lip, or tongue tissue, which can cause trauma and delay healing.
For most patients, this means waiting at least one to two hours following the procedure. If no anesthesia was used, the waiting period is minimal, but caution is still advised to allow minor gum irritation to settle. The total waiting time can be longer if the procedure involved extensive treatment or a stronger dose of anesthetic.
Immediate Post-Procedure Dietary Guidelines
For the first 24 to 48 hours following the deep cleaning, the focus should be on consuming foods and liquids that require minimal chewing and will not irritate the treated gum tissues. Soft, nutrient-dense options are best for supporting the body’s natural healing process. Examples of safe foods include mashed potatoes, scrambled eggs, well-cooked pasta, yogurt, applesauce, and smoothies made without seeds.
Patients must avoid foods that can compromise the healing sites or cause discomfort. Strictly avoid hard, crunchy, or sticky foods, such as nuts, chips, popcorn, or caramels, as these can easily become lodged in the treated pockets. Highly acidic or spicy foods, including citrus fruits, tomatoes, and hot sauces, should also be avoided because they can cause a burning sensation on sensitive tissues.
Temperature control is also a consideration immediately following the procedure, as the teeth and gums may be temporarily sensitive. Extremely hot foods or beverages, like coffee or soup, should be avoided for at least 24 to 48 hours because heat can increase swelling and sensitivity. Similarly, very cold items may trigger discomfort. Lukewarm or room-temperature liquids and soft foods are the best choice during this initial healing phase.
Essential Non-Dietary Aftercare Instructions
Beyond managing food intake, several non-dietary measures are important for a smooth recovery and successful healing of the gums. Brushing should be done gently with a soft-bristled toothbrush for the first day or two, being careful around the treated areas. Flossing near the site should be approached with caution, and patients should follow their dental professional’s instructions on when to resume a normal routine.
Avoid using any tobacco products, including smoking and vaping, for at least 72 hours, as tobacco significantly delays tissue healing and increases the risk of infection. Patients should also refrain from using straws immediately after the procedure. The suction created by using a straw can potentially dislodge forming blood clots or irritate the tender gum tissues.
For managing common post-procedure discomfort, over-the-counter pain relievers such as ibuprofen or acetaminophen are often recommended. Rinsing the mouth gently with a warm salt-water solution—one teaspoon of salt dissolved in eight ounces of warm water—three to four times a day can help soothe the tissues and promote cleansing. Attending the scheduled follow-up appointment, often a periodontal maintenance visit, is important to allow the dental team to evaluate the healing and long-term success of the deep cleaning.
