Salt water,: specifically warm salt water. Rinsing your mouth out with warm salt water several times per day, especially after eating is recommended for preventing or helping to heal infection.

Neither: I would speak to your Dentist, but I like Chlorhexidine quite a bit and use it regularly with my patients for most all oral surgery procedures. It is much better at what you need to see happen after surgery than either hydrogen peroxide or salt water. Cheers!

Post Op Instructions: Your own dentist would be the best one to suggest post operative care based upon your specific circumstances. Call and ask. Make sure you return for follow-up aftercare. Tooth infections also require antibiotic coverage.

Both are good: 1. Hydrogen Peroxide -1-3%. Make sure to keep it in the mouth and allow that to stay in and around the surgical site for 30 seconds. 2) Follow with a rinse of 1 cap warm water mixed with a 1/2 teaspoon of salt.

Post ext rinse: Either diluted hydrogen peroxide or salt water will work--Hydrogen peroxide may dissolve the clot or dissolve resorbable sutures quicker than desired. Practice good home care, keep your mouth clean and rinse after you eat. Happy healing!

Salt water: ..but not too soon after the surgery so you don't dislodge the blood clot. Hydrogen peroxide is a potent oxidant and is primarily indicated for a condition called Acute Necrotizing Ulcerative Gingivitis or Trenchmouth. It needs to be diluted before oral use. Warm salt water OTOH, is benign and quite helpful in your situation.

Oral Rinses: Good day Michael; The best mouth wash for tooth infection is to contact your dentist ASAP and have the dental issue treated! Chlorhexidine Gluconate a 0.12% oral rinse (Peridex-brand) reduces bacteria in the mouth. The rinse may be very helpful in comforting red and swollen gums.

Salt water: Years ago, hydrogen per oxide was commonly used for oral health issues. Through research we have found it is more harmful to the oral tissue with long term use. So avoid using it. Warm salt water rinses and sticking to a soft food diet will work the best. Make a consultation with your oral health care provider for an exam to help determine the best treatment options for you long term.

Peroxide: I prefer hydrogen peroxide because of the bubbly effervescent quality that seems to remove particles more deeply. I tell my patients to dilute it 50/50, equal parts water to peroxide and don't swallow it. Brushing your teeth right after takes away the bad taste

Salt water: I would recommend salt water rinse 48 hours after extraction.

Both are helpful: H2O2 is good to break up the blood clots around the mouth and is antimicrobial. Salt water helps to draw the excess fluid out and decrease swelling

Hydrogen peroxide: is a better antiseptic. Tooth and Gum Tonic is a good all natural antiseptic month rinse.
