In general, the above situation is likely just a coincidence.
It is recommended to maintain oral hygiene even when experiencing mouth sores, as they typically heal on their own within 1 to 2 weeks.

More Info

It is not uncommon to experience some discomfort or even minor mouth sores after a dental cleaning, especially if the cleaning was thorough or if you have underlying gum issues. Dental cleanings often involve the removal of plaque and tartar, which can irritate the gums, particularly if they are already inflamed or sensitive. However, the appearance of significant sores or "holes" in the mouth, especially one day after a cleaning, should be taken seriously.

Mouth sores can arise from various causes, including trauma to the soft tissues during the cleaning process, allergic reactions to dental materials, or even infections. If the cleaning was particularly aggressive, it might have caused some minor abrasions or irritation that could lead to sores. Additionally, if you have any existing gum disease or periodontal issues, the cleaning might exacerbate these conditions, leading to more pronounced symptoms.

In your case, since you mentioned that the sores are quite severe, it is advisable to monitor the situation closely. While minor irritation can heal on its own within a week or two, more severe sores or those that do not improve could indicate a need for further evaluation. Maintaining good oral hygiene is crucial during this time. Rinse your mouth with warm salt water to help soothe the area and promote healing. Avoiding spicy, acidic, or abrasive foods can also help reduce irritation.

If the sores persist beyond a couple of weeks, worsen, or are accompanied by other symptoms such as fever or swelling, it would be prudent to consult a dentist. They can assess the situation and determine if there is an underlying issue that needs to be addressed, such as an infection or a reaction to the cleaning materials used.

In summary, while some discomfort after a dental cleaning is normal, significant sores or "holes" in the mouth warrant attention. Keeping the area clean, using saltwater rinses, and avoiding irritating foods can help. If symptoms persist or worsen, seeking professional dental advice is essential to ensure proper treatment and care.
