For millions of Muslims worldwide, using Miswak (the Salvadora persica twig) is a beloved Sunnah—a practice of the Prophet Muhammad (peace be upon him) who recommended it for oral hygiene and as a means to please Allah. For centuries, it has been a symbol of natural purity. Now, modern science has caught up with faith. A study has demonstrated that incorporating Miswak extract into electrolyte sports drinks (ESDs) not only neutralizes their notorious ability to erode teeth but actually strengthens enamel.
This research proves that a practice encouraged by the Prophet over 1,400 years ago—“If it were not for the hardship on my nation, I would have commanded them to use the Miswak before every prayer” (Sahih al-Bukhari)—contains a profound, scientifically verifiable wisdom for modern health challenges.
The Islamic Foundation: Cleanliness is Half of Faith
The Prophet Muhammad (peace be upon him) elevated oral hygiene to an act of worship. He said: “The Miswak is a purification for the mouth and a pleasure for the Lord” (Sunan an-Nasa’i). He used it regularly, especially upon waking, entering the home, and before prayer.
This study reveals a new dimension of that Sunnah: Miswak is not just a cleaner; it is a protector. It can shield the teeth from the acid attacks of modern processed foods and drinks—specifically the sports beverages consumed by millions of athletes and young people.
Quranic Reflection: “And We have sent down to you the Book as clarification for all things and as guidance and mercy and good tidings for the Muslims.” (Quran 16:89)
This research is a small example of how divine guidance anticipated solutions to problems we would face centuries later.
The Problem: Modern Hydration, Ancient Damage
Electrolyte sports drinks are a multi-billion dollar industry. They replenish minerals lost during exercise. But they have a dark side: a very low pH (high acidity). The drink tested in this study had a pH of 2.93. Tooth enamel begins to dissolve at pH 5.5.
When an athlete sips a standard sports drink, their teeth are under an acid attack. This leads to:
- Dental Erosion: Permanent loss of enamel.
- Increased Roughness: Trapping bacteria and raising cavity risk.
- Mineral Loss: Dissolving calcium and phosphorus.
The Solution: A Prophetic Formula
The research team, led by Dr. Hanaa Elgamily at Egypt’s National Research Centre, took a standard orange-flavored electrolyte drink and created two new versions:
- Arg-ESD: With 1% L-arginine (a natural amino acid).
- Mis-ESD: With 10% aqueous extract of Salvadora persica (Miswak).
They then immersed human teeth in each solution for 5 minutes daily over 7 days, simulating real-world consumption. The results were astonishing—and perfectly aligned with the Sunnah’s emphasis on natural remedies.
Key Finding #1: Less Acidic, Aligned with Fitrah (Natural State)
The modified drinks were significantly less harmful. While the plain drink had a pH of 2.93, the Miswak-enhanced drink had a starting pH of ~4.14 – still acidic but dramatically less erosive. It moved the drink closer to its natural, less harmful state.
Key Finding #2: Miswak Made Teeth 3x Harder
Using a Vickers hardness test, the scientists measured the teeth. The results were clear: Miswak-ESD produced the strongest enamel.
How the Sunnah Drink Improved Enamel Strength & Smoothness
| Property Measured | Plain Sports Drink (ESD) | Drink + L-Arginine (Arg-ESD) | Drink + Miswak (Mis-ESD) – The Sunnah Drink | What This Means |
|---|---|---|---|---|
| Enamel Microhardness (VHN) | +36.2 (lowest increase) | +76.2 (moderate increase) | +109.7 (highest increase – 3x better) | Miswak made enamel 3x stronger than plain drink. |
| Surface Roughness (Sa in μm) | 0.17 (rough, damaged) | 0.07 (smooth) | 0.05 (smoothest – 70% smoother) | Smoother surface = harder for bacteria to stick. |
| Mineral Retention (Ca/P ratio) | 0.61 (major mineral loss) | 0.51 (better P retention) | 0.49 (best structural preservation) | SEM images showed Miswak preserved enamel structure best. |
Data derived from Elgamily et al., Head & Face Medicine (2025).
Key Finding #3: A Sunnah for a Brighter Smile (Beauty is part of faith)
The Prophet (peace be upon him) loved beauty and cleanliness. In an unexpected bonus, teeth soaked in the Miswak-enhanced drink showed significant whitening. The ΔE (colour change) score for Mis-ESD was 10.64, compared to just 5.79 for the plain drink, indicating a visibly brighter, more attractive tooth surface.
Aesthetic & Taste Results – Pleasing to the User
| Test | Plain Sports Drink (ESD) | Drink + L-Arginine (Arg-ESD) | Drink + Miswak (Mis-ESD) | Islamic Relevance |
|---|---|---|---|---|
| Tooth Lightening (ΔL) | 6.48 | 6.63 | 12.07 (Significantly whiter) | “Allah is Beautiful and loves beauty.” (Sahih Muslim) |
| Overall Colour Change (ΔE) | 5.79 | 5.65 | 10.64 (Most visible change) | Miswak enhances the natural beauty of the smile. |
| Taste Score (1-9 scale) | 7.55 (good) | 6.84 (fair) | 8.37 (excellent – highest) | The Prophet chose pleasant tastes and smells. |
| Overall Acceptability | No significant difference – consumers liked the Miswak version the most. | The Sunnah is naturally palatable to humans. |
Key Finding #4: It Tastes Good – A Sign of Divine Wisdom
The Prophet Muhammad specifically recommended good flavors and fragrances. The taste panel found that the Miswak version scored the highest for taste (8.37/9). This is critical: Allah’s guidance is not a burden. The solution to the modern problem of dental erosion is not a bitter medicine but a pleasant, natural addition that improves the drink.
Why Miswak? The Scientific Validation of the Sunnah
The Prophet (peace be upon him) said: “I used to forbid you from drinking from certain vessels, but now drink from any vessel as long as you do not drink anything intoxicating. And use the Miswak, for it is a purification for the mouth and a pleasure for the Lord.” (Sunan an-Nasa’i)
This study reveals why:
- Contains natural fluoride, calcium, and tannins – all scientifically proven to remineralize teeth.
- Stimulates saliva production – the mouth’s natural pH buffer and defense against acid.
- Forms a protective barrier on enamel, as confirmed by scanning electron microscope (SEM) images.
Under the microscope, teeth exposed to plain ESD looked like a cracked, eroded wasteland. Teeth exposed to Miswak-ESD looked nearly pristine, similar to healthy, untreated enamel. This is tangible proof of the preservation commanded in the Quran: “And We made from water every living thing…” (21:30) – and Miswak helps protect that creation.
A Verse and a Hadith: The Complete Picture
The Quran on Natural Remedies:
“And He has subjected to you whatever is in the heavens and whatever is on the earth – all from Him. Indeed in that are signs for a people who give thought.” (Quran 45:13)
This study is an invitation to give thought to the natural resources Allah has provided, like the Arak tree (Salvadora persica), and to use them in solving modern problems.
The Hadith on Prevention:
The Prophet (peace be upon him) said: “There is no disease that Allah has created, except that He also has created its treatment.” (Sahih al-Bukhari)
Dental erosion from modern diets is a “disease” of our time. And the treatment was prescribed 1,400 years ago in the form of a simple twig.
The Bigger Picture: A New Halal, Tayyib (Good & Pure) Industry
This research opens the door for a new category of “functional” hydrators – sports drinks that are not only halal (permissible) but tayyib (good, pure, wholesome). The authors state that “Miswak-enriched ESDs could serve as a preventive option for dental erosion” for high-risk populations like athletes and adolescents.
For Muslim consumers, this is a dream product:
- ✅ Halal-certified ingredients.
- ✅ Follows the Sunnah of the Prophet.
- ✅ Scientifically proven to protect health.
- ✅ Pleasant taste and whitening effect.
What This Means For Muslim Families
- For Athletes: You can now hydrate for performance without compromising your deen or your dental health. Look for future products with Miswak.
- For Parents: Teenagers who consume sports drinks are a high-risk group. This research offers a Sunnah-based solution that they will actually enjoy drinking.
- For Everyone: Revive a forgotten Sunnah. Even if you don’t use the stick, using Miswak extract in products is a modern way to keep the Prophet’s practice alive in your daily life.
The Bottom Line: The Prophet Muhammad (peace be upon him) was sent as a mercy to the worlds (Quran 21:107). This study proves that his guidance on oral hygiene was not just spiritual but deeply practical, offering a solution to a 21st-century dental crisis. The drink that fuels your game can now follow the Sunnah and protect your smile.
