Oral health is an integral part of our overall well-being. The choices we make daily, including how we consume our drinks, can have a significant impact on our dental health. One habit that has been touted for its supposed oral health benefits is drinking through a straw. Is drinking with a straw beneficial? Can you drink sodas and other low pH beverages without harming your teeth? How to drink with a straw properly? We explore whether drinking with a straw is indeed better for your teeth and under what circumstances it can be beneficial.

The Impact of Beverages on Dental Health

First, let’s understand how certain drinks affect dental health. Beverages like sodas, fruit juices, and sports drinks often contain high levels of sugar and acids. These substances can contribute to tooth decay and erosion. When you drink these beverages directly from a glass, can, or bottle, they have more contact with your teeth.

The Science Behind Straws

Using a straw when drinking can minimize contact between the beverage and your teeth. The straw essentially channels the liquid directly into your mouth, bypassing the teeth to a great extent. This can be particularly beneficial in reducing the risk of decay and erosion associated with sugary and acidic drinks.

Types of Straws and Positioning

Not all straws are created equal, and how you use them can also make a difference. A narrower straw will limit the volume of liquid with each sip, which may be beneficial. Positioning the straw towards the back of your mouth can further reduce contact with your teeth. However, be cautious about the material of the straw – reusable straws made from metal or glass are more eco-friendly compared to single-use plastic straws.
Drinking with a straw can also help prevent staining from drinks like coffee and wine. Just as with acidic drinks, the straw can minimize contact with the teeth, which can be beneficial in maintaining the natural color of your teeth.

Limitations and Considerations

While straws can be beneficial, they are not a cure-all. Drinking sugary or acidic drinks through a straw still introduces these substances into your mouth, which can affect not just your teeth but your overall oral environment. It’s also worth noting that while straws may reduce contact with the teeth, they do not eliminate it entirely.
Additionally, excessive use of straws can potentially cause you to take in more air, which might contribute to bloating and gas.

Incorporating Straws into a Holistic Oral Care Routine

Using a straw can be one component of a holistic approach to oral care. It’s also essential to maintain proper oral hygiene by brushing twice a day and flossing daily. Additionally, consuming a balanced diet low in sugary and acidic foods and beverages is crucial. Regular dental check-ups are also an integral part of maintaining good dental health.
While considering the use of straws, it’s also important to think about the environmental impact. Plastic straws are non-biodegradable and contribute to pollution. Opt for reusable straws made from sustainable materials, such as stainless steel, bamboo, or silicone.

Is drinking with a straw better for your teeth?

Yes, drinking with a straw can be better for your teeth, especially when consuming beverages that contain acids or sugars.
Here’s why:

  • Reduces Direct Contact with Teeth: When you drink with a straw, the liquid is directed towards the back of your mouth, so it has less contact with your teeth. This is particularly beneficial with acidic or sugary drinks that can erode enamel and lead to cavities.
  • Prevents Staining: Beverages like coffee, tea, and wine can stain your teeth. Using a straw can minimize the contact these drinks have with your teeth, potentially reducing staining.
  • Helps Sensitive Teeth: If you have sensitive teeth, a straw can help by directing cold or hot liquids away from sensitive areas, minimizing discomfort.
  • Controlled Drinking: A straw allows you to sip slowly, which may limit the exposure time of the teeth to harmful substances in the beverage.

However, it’s essential to recognize some potential downsides as well:

  • Environmental Impact: Plastic straws can be harmful to the environment, so if you’re going to use a straw, consider reusable options like stainless steel, glass, or silicone straws.
  • Potential Health Concerns with Plastic Straws: Some plastic straws may contain harmful substances like BPA, so it’s wise to choose straws made from safe materials.
  • Not a Substitute for Good Oral Hygiene: While using a straw may help reduce exposure to harmful substances, it’s not a replacement for proper oral care. Regular brushing, flossing, and dental check-ups are still crucial.
  • May Not be Suitable for All Beverages: Drinking thicker liquids or enjoying the full flavor of some beverages might be challenging with a straw.

In summary, using a straw can have some dental benefits, mainly when drinking sugary or acidic beverages. However, it is essential to be mindful of the type of straw used and to continue practicing good oral hygiene.

How straws can reduce teeth stains? Does using a straw help with dental staining?

Straws can help reduce teeth stains by minimizing the contact that staining liquids have with the teeth.
Here’s how it works:

  • Directing Liquid Away from the Front Teeth: When you drink with a straw, the liquid is typically directed towards the back of your mouth. As a result, it bypasses the front teeth, which are the most visible and most prone to noticeable staining. Beverages like coffee, tea, red wine, and colas that contain tannins and chromogens are notorious for staining teeth. By limiting the exposure of these substances to the front teeth, a straw can reduce the staining effect.
  • Limited Exposure Time: Sipping through a straw allows you to control the flow of the liquid, potentially limiting the time your teeth are exposed to staining substances. The less time these compounds have to interact with the enamel, the less opportunity there is for stains to form.
  • Prevention of Acidic Erosion: Many staining beverages are also acidic, which can erode the enamel, exposing the underlying dentin, which is more prone to staining. By directing these liquids away from the teeth, a straw can help protect the enamel, indirectly reducing the risk of staining.

However, it’s worth noting that a straw may not entirely prevent staining, especially if you consume staining beverages frequently or in large quantities. Also, the effectiveness of the straw in preventing stains can depend on how you use it. If you place the straw directly behind your front teeth, it may not be as effective in preventing stains as when you direct it further back into your mouth.
While using a straw can help minimize staining, other strategies, such as rinsing your mouth with water after consuming staining beverages, using whitening toothpaste, or seeking professional dental cleaning and whitening treatments, are also effective in maintaining a bright smile.

Drinking tea or coffee with a straw

Drinking tea with a straw might seem unconventional, but it can offer certain benefits, especially if you’re concerned about your dental health.
Here’s a breakdown of why you might consider using a straw for tea:

  • Reduced Staining: Tea contains tannins, which can stain teeth over time. Drinking tea through a straw can minimize the contact between the tea and your teeth, reducing the risk of staining.
  • Protects Sensitive Teeth: If you have sensitive teeth, using a straw can help direct the hot or cold liquid away from sensitive areas, minimizing discomfort.
  • Control Over Temperature: Sipping tea through a straw can allow you to control how much of the hot liquid comes into contact with your mouth at once, potentially making it easier to drink if it’s very hot.


  • Affects Taste: Drinking tea through a straw may alter the way you perceive its flavor, as you won’t be sipping and aerating it in the same way you would when drinking from a cup. The full range of aromas and flavors may not be as perceptible.
  • Environmental Considerations: If you are using single-use plastic straws, there is an environmental impact to consider. Reusable straws made of materials like stainless steel, silicone, or glass are a more sustainable option.
  • Possibly Awkward: Using a straw for hot beverages like tea can be tricky and may feel awkward, especially if the tea is scalding hot.
  • Potential Safety Concern: Extremely hot liquids can pose a safety risk if you’re using a straw, as they can scald the throat or mouth if consumed too quickly. It’s advisable to make sure the tea is at a drinkable temperature before using a straw.
  • Compatibility with Additives (when drinking coffee): If you add sugar, milk, or cream to your coffee, using a straw might affect how well these mix with the coffee. The experience of tasting these additives might be different when sipping through a straw.

Drinking tea or coffee with a straw can be beneficial in terms of reducing teeth staining and protecting sensitive teeth. However, it may not be suitable for everyone or every situation, especially if you are particular about the taste experience or if the tea is too hot. If you do decide to use a straw, consider reusable options to minimize environmental impact.

How to drink in straws without touching teeth

Drinking through a straw without allowing the liquid to touch your teeth can be a bit tricky, but it is possible with some practice and careful positioning.
Here’s how you might try to do it:

  • Position the Straw Carefully: Place the straw farther back in your mouth, aiming for the area between your molars and the back of your tongue. By positioning the straw here, the liquid can bypass the front and middle teeth, reducing contact.
  • Sip Slowly: Sipping slowly helps control the flow of liquid, giving you more control over where it goes in your mouth.
  • Use a Longer Straw: A longer straw can be easier to position farther back in the mouth, reducing the risk of the liquid touching the teeth.
  • Practice Swallowing Technique: You’ll likely need to adapt your swallowing technique to prevent the liquid from swishing around your mouth and touching your teeth. Try to swallow the liquid directly from the straw, bypassing the teeth as much as possible.
  • Consider Straw Design: Some straws are designed with features that could make this process easier. For instance, a straw with a bend or a flexible section could be positioned in a way that directs the liquid more precisely.
  • Avoid Extremely Hot or Cold Liquids: Extremely hot or cold liquids could be uncomfortable or even harmful if they contact sensitive areas of your mouth directly, so be cautious with the temperature of what you’re drinking.
  • Be Patient and Cautious: It might take some practice to get used to drinking this way, especially without letting the liquid touch your teeth. Be patient and go slowly to find what works for you.

Keep in mind that this technique might not be suitable for all types of beverages, especially thick or textured drinks, and it may alter your experience of the flavor. Additionally, it’s not a foolproof method for completely avoiding contact with the teeth, especially if the drink is swirled around the mouth before swallowing. If your main concern is dental health, combining this technique with good oral hygiene practices will be the most effective approach.

How much does a straw help drinks? Does drinking out of a straw help teeth?

Drinking out of a straw can offer some benefits to your teeth, particularly when consuming beverages that are acidic, sugary, or prone to causing stains.
