Benefits of Walnut Bark Powder for Oral Hygiene

  • Cleans and whitens the teeth by supplementing the composition of healthy enamel (not by bleaching). Consequently it takes several months for the full colour improvement to take place, although you will begin to see the improvement much sooner.
  • Strengthens and tightens gums, helping to prevent bleeding gums. Reduces inflammation of the gums.
  • Inhibits microorganisms representing Gram-positive bacteria like (Staphylococcus aureus and Streptococcus mutans), Gram negative bacteria like (Escherichia coli and Pseudomonas aeruginosa) and pathogenic yeast (Candida albicans) due the presence of juglons and glycocides.
  • Increased pH (making the saliva less acid) and reducing corrosion of enamel and dentine.
  • Reduces the adherence of bacteria by the presence of Polyphenols.
  • Keeps the mouth feeling fresh after use as a mouth wash for up to 3 hours after rinsing by reduced total streptococcal counts in salivary samples.

Walnut Bark Dry Tooth Powder

Wet your toothbrush and dip it into the powder. Use for cleaning and whitening the teeth. Or mix with other dry ingredients such as ultra ventilated clay powder, finely ground sea salt, etc.

Toothpaste Mix with Walnut Bark Powder

with a little water or mix with coconut oil. Make up small quantities at a time.

Mouth Wash with Walnut Bark Powder

Make up a solution containing 15g of Walnut Bark and 100ml of boiled water. Once cool enough to use, swish around the teeth for several minutes. This is very beneficial for the gums. Follow by rinsing.

Interim Treatment Loose Teeth

It is really important to make sure you are under the care of a dentist, but as an interim measure, use your finger to gently apply walnut bark powder to the gums around the loose teeth at night. Rinse out in the morning.

Interim Treatment Gum Abscesses

Again see a dentist and take their advice. In the meantime, cut a small piece of muslin cloth, fold walnut bark powder inside the cloth and place it next to the effected gum. Leave in place except for when eating of drinking and change two or three times a day.

    I just want to say, how happy I am with the walnut bark powder and green clay. After seeing a dentist about a poorly molar which will at some point need removing, my gum inflamed into a huge boil, the largest I have ever seen. I got some relief by putting the walnut bark powder on the swollen gum and then used it as a mouthwash. After a day or too, I decided to try the green clay too – so I put a blob of green clay mixed with a little walnut bark powder and a little bit of turmeric on the gum, removed it after 15 minutes and repeated. Almost straight away I could feel the heat reducing. I then slept with the green clay mix next to the tooth. To my utter amazement and great relief, the huge boil shrunk back completely. I have continued with the treatment a bit more as I am going travelling soon and don’t want it to come back. Not only does the whole tooth feels more stable, resilient and healthy again but all my gums feel calmer and healthier than they have in a long time. I am so grateful. I wonder how many people could benefit from these old natural remedies? Yes, I have packed the walnut bark powder and the green clay already!

    I’ve got to tell you that this Walnut Bark Powder is absolutely fantastic. I felt it working on my gums the first time I used it. I have tried lots of products over the years from healthfood shops and nothing has helped like this. My gums look and feel so much better already. I’m just amazed.
