Is Red Wine Good for Your Teeth?
Red wine has previously been linked to a range of supposed health benefits, from helping the heart to lowering the risk of diabetes.
Now a new study suggests it contains chemicals that can help in the fight against tooth decay and gum disease.
Researchers found compounds from the drink, known as polyphenols, helped fend off harmful bacteria in the mouth.
Not in any practical sense. A 2018 laboratory study found that two compounds from red wine made some mouth bacteria less able to stick to gum cells in a dish. That is an interesting clue for future products, but wine itself is acidic, it stains, and drinking more of it is not a way to protect your teeth or gums.
What did the study test?
Researchers in Spain asked whether polyphenols, plant compounds found in red wine, could stop harmful mouth bacteria from attaching to gum tissue. Attachment is the first step in forming plaque.
They grew human gum cells (gingival fibroblasts) in the lab and exposed them to three bacteria linked to dental disease: Streptococcus mutans, a main cause of tooth decay, and Porphyromonas gingivalis and Fusobacterium nucleatum, which are linked to gum disease. They tested two individual wine polyphenols, caffeic acid and p-coumaric acid, along with grape seed and red wine extracts.
What did they find?
All of the compounds and extracts reduced how well the bacteria stuck to the gum cells.
The two individual acids worked better than the extracts.
When the acids were combined with Streptococcus dentisani, a bacterium being studied as an oral probiotic, they were even better at blocking S. mutans.
The cells and bacteria began breaking the polyphenols down, which suggests the mouth starts to process these compounds.
What are the limits?
This was a laboratory model. No one drank wine, no teeth or gums were examined, and the amounts tested do not tell us what happens in a real mouth after a glass. The authors themselves said more work is needed to explain the effect. A lab result like this is a reason to keep studying polyphenols, perhaps for future rinses or other products. It is not a reason to change what you drink.
What does this mean for your teeth now?
Wine is acidic, and frequent sipping softens enamel over time. Red wine also stains teeth. Alcohol carries its own health risks. The National Cancer Institute lists drinking alcohol as a risk factor for cancers of the mouth and throat. If you drink wine, a few habits help:
Have it with a meal rather than sipping over a long evening.
Rinse with water afterward.
Keep cleaning between your teeth and using fluoride toothpaste.
Polyphenols are also found in tea, coffee, berries, grapes, cherries and beans. Some of these stain or are acidic too, so the same habits apply. Our guide to foods for healthy teeth covers diet in more detail, and sparkling water is a common question for people cutting back on wine.
If you are in Jacksonville and have questions about staining or enamel wear, contact our office or arrange a dental examination.

Was Paul Revere a Dentist? The First American Forensic Dental Identification
Paul Revere inadvertently became America’s first forensic dentist when he was given the gruesome task of identifying the body of Dr. Joseph Warren, the man who sent him on his famous “midnight ride.” Warren was struck down by a British bullet during the Battle of Bunker Hill on June 17, 1775 and his corpse was buried in a mass grave. When Warren’s family unearthed the grave nine months later, visual identification of the bodies inside was near impossible because they had decomposed. So Revere, the man who crafted the slain officer’s false teeth, was asked to locate Warren’s remains by finding the ivory dentures he crafted and wired to Warren’s jaw.

Paul Revere, silversmith and patriot, is widely regarded as America’s first forensic dentist after identifying Dr. Joseph Warren through dental prosthetics following the Battle of Bunker Hill.
Yes. Paul Revere, the Boston silversmith remembered for his midnight ride, also made and fitted artificial teeth. In 1776 he identified the remains of his friend Dr. Joseph Warren by recognizing a dental bridge he had made for him. Historians often describe it as the first forensic dental identification in America.
How did Paul Revere become a dentist?
Revere was a skilled metalworker, and in colonial Boston that made dental work a natural sideline. He learned to make and fit false teeth from John Baker, a surgeon-dentist working in Boston. When Baker left for New York, Revere advertised in 1768 that he could care for Baker's work, and he placed dental advertisements again in 1770. His notices said his artificial teeth looked natural and let people speak normally. [1] [2]
His dentistry was simple by today's standards. He carved replacement teeth from ivory or animal tooth and fastened them to neighboring natural teeth with wire. He did not do fillings or surgery as a modern dentist would.
How did Revere identify Joseph Warren?
Dr. Joseph Warren was a Boston physician and a leader of the patriot cause. Shortly before the war began, Revere made him a small bridge that replaced his upper left canine and first premolar with ivory teeth held in place by wire. [1]
Warren was killed at the Battle of Bunker Hill on June 17, 1775, and was buried with other soldiers in a shallow grave. After the British left Boston in March 1776, Warren's family and friends went looking for his body. By then, about nine months after the battle, his face could not be recognized. Revere examined the remains and found the bridge he had made. Warren was reburied with honors in April 1776. [1] [3]
Why does this story matter to dentistry today?
Teeth and dental work are among the most durable parts of the body. They survive heat, time and trauma better than most tissues, and every mouth is different. That is the basis of forensic odontology, the use of dental evidence to identify people.
Modern forensic dentists compare dental records, X-rays, fillings, crowns and implants with remains. They help identify victims of disasters, accidents and crimes. The tools are far better than Revere's memory of his own handiwork, but the idea is the same: the details of a person's teeth and dental work are individual.
It is also a reminder of why careful records matter. In our office, photographs, X-rays and, when they are clinically needed, 3D images document your teeth so we can see how they change over time.
