Teeth Whitening Side Effects – Why Your Teeth Hurt After Whitening And How To Avoid It

Millions of people across the world have now had their teeth whitened. Most do not experience any downsides significant enough to deter them from whitening again. Teeth whitening has become one of the most common procedures performed in modern dentistry. However, as with any medical procedure there can be some side effects. Most are minor but the improper use of over the counter whitening products like peroxide gels can cause sensitivity, pain and even chemical burns.

What Are The Side Effects Of Whitening Your Teeth?

The main side effect of teeth whitening is increased tooth sensitivity. This is the most commonly experienced downside of dental bleaching with peroxide. This means that you’ll experience some discomfort when your teeth are exposed to extreme temperatures, like when you eat ice cream or hot soup. Fortunately this is temporary, and will stop some time after you end your treatment course with whitening gel. Toothpastes that include peroxide for improved whitening do not use high enough concentrations of peroxide to cause this side effect in most people.

Gum irritation is the other most common side effect of whitening. This is caused by getting the powerful chemicals used in the whitening gels into contact with your gums. Most professional teeth whitening treatments at a dentist’s office will use custom fitted trays to hold the whitening gel in contact with your teeth, while keeping it away from your gums. Since at home whitening products use one size fits all trays, you can easily expose your gums to the bleaching agent by filling the tray with too much gel. Carefully follow the directions of the whitening gel you purchase exactly as they are written and do not apply more than a small teardrop-sized amount to the tray. This will help you avoid irritating your gums.

Less common and easily avoided side effects of teeth whitening gels include stomach irritation and nausea from swallowing the gel. Limiting the amount you use and simply avoiding drinking and eating while whitening will prevent this. Unfortunately, tooth sensitivity is somewhat harder to avoid for people susceptible to it.

Why Does Teeth Whitening Cause Increased Tooth Sensitivity?

Whitening gels that use peroxide to bleach the enamel of your teeth can also open up pores in the structure of your teeth, exposing the inner dentin layer to your foods and drink. Dentin is made up of tiny tubes called dentinal tubules, and peroxide causes a chemical reaction that opens up these tubes. This is what exposes the root nerve of your tooth to external temperature influences. Even cold winter air can cause painful sensitivity if you suffer from this side effect. The pain will pass as the tooth nerve and dentin warm or cool back towards body temperature, but the discomfort can be a great annoyance until then.

If you know you already suffer from sensitive teeth, use a good restorative toothpaste to improve the structure of your teeth and reduce sensitivity before beginning an at home whitening treatment. Consider using a whitening gel with a reduced concentration of peroxide to try to avoid the sensitivity side effect altogether, but be aware this will require more sessions to whiten your teeth.

Once you’ve gotten the whitening results you wanted to achieve and you discontinue use of the bleaching gel, the increased sensitivity will diminish and eventually cease. If the increased dental sensitivity doesn’t fade away quickly enough for you, simply begin using a restorative toothpaste that contains fluoride and NovaMin daily to lessen your tooth sensitivity. You’ll be able to once again eat and drink what you like without experiencing discomfort. Just keep in mind that you should avoid heavily pigmented foods to keep from staining your teeth once again, and follow up on the whitening gel treatment with a good whitening toothpaste to keep your new, improved smile looking great.

Why Does Teeth Whitening Cause Gum Irritation?

The high concentration of the powerful peroxide chemical found in teeth whitening products like gels and strips can cause painful chemical burns and irritation if the peroxide is exposed to the soft tissue of your gums. This gum irritation is usually temporary and will stop a few days after you discontinue use of the whitening gel. Always follow the directions of any whitening products you buy carefully to whiten your teeth safely and prevent side effects. The most important tip to prevent gum irritation is to make sure you only use the amount of gel specified in the directions and wipe away any excess that touches your gums. Usually all you will need is a small teardrop-sized amount per tooth.

The trays that are used with whitening gels can irritate gums all by themselves, as the over the counter versions are not individually fitted. The tray can rub up against the gums, irritating the sensitive tissue. Limiting the amount of time you wear the tray can reduce this annoyance, but it will take more sessions to whiten your teeth to your desired shade.

Different people have different reactions to the various levels of peroxide found in different whitening products. If you are concerned about the side effects of peroxide whitening, I recommend using whitening strips or gels containing a lower concentration of carbamide peroxide to avoid gum and tooth irritation. This allows you to work your way up to the concentration of peroxide you need to whiten your teeth to the level you want, without immediately purchasing the strongest peroxide product available, which is most likely to cause side effects.

How Can You Avoid These Side Effects and Still Whiten Your Teeth?

Buy a whitening gel from a well-reviewed and reputable company, preferably one that makes all its products in the USA, like my preferred brand does. Always follow the directions exactly as they are written, and do not overuse the whitening gel. Remember that adding more gel and overfilling the tray will not get you whiter teeth, but will expose your gums to potential chemical burns and irritation! Consider the option of using a low concentration peroxide gel and working your way up to the concentration needed to get the shade of white teeth you desire. Remember that even whitening at a dental office can result in painful or annoying side effects like increased sensitivity. This is just a byproduct of the peroxide that is used by all conventional whitening methods to bleach your teeth.

The Step – By – Step Process of Getting a Brazilian Bikini Wax


NSW Health regulations and code of best practice state the following:

• The therapist must wash her hands before and after each treatment;

• Wear single use gloves during all waxing treatments, to be disposed of immediately after treatment (vinyl or latex);

• The area to be treated must be cleansed before all waxing treatments;

• Disposable spatulas must be used and only dipped once into the wax pot;

• Wax used for hair removal on a client must be disposed of immediately and not reused or recycled;

• Clean linen, garments or towels should be used for each client

• Work area and equipment must be wiped over using a hospital grade disinfectant.

• All non disposable implements must be sterilized (tweezers, scissors);


• Client consultation: discuss with your client exactly how much hair they would like removed, e.g, landing strip, shaping, full hair removal. Ensure this is clear before commencing treatment and record this information on the appropriate client file;

• Contraindications: always check prior to proceeding with treatment. The addendum to these notes provide a suggested checklist for display in the treatment room. Ensure you clients are aware of any conditions that may affect the treatment.

• Client comfort: for both the client and the therapist it is best to provide the client with a disposable elasticized G-String. Hygiene wipes should also be offered. We recommend the use of a G-string not only for the modesty of the client, but equally as importantly, it enables the therapist to support and stretch the area being waxed and minimises direct contact with the genital area;

• Cleanliness: Wash & dry hands, put on disposable gloves and apply pre-wax cleanser to the area. This will remove surface bacteria, perspiration and moisture residue;

• Clipping: Check the length of hair and if necessary, trim the area with safety scissors and/or electric clippers. This will result is a more comfortable treatment for the client, less wax being used and a better result;

• Apply pre-waxing oil to the entire area to be waxed. Pre waxing oil can be re-applied throughout the treatment if necessary. Remember, pre-waxing oil enables the wax to grip the hair and not the skin. It also improves elasticity of the wax and minimizes wax breakage.


Hot wax removes hair that is 1 mm long and often shorter. Strip wax can be used for brazilian waxing, however, the “stripping” technique can be more traumatic for the client and can also result in skin being lifted or hair breakage. It is for these reasons we endorse hot waxing only for brazilian waxing.

• Work from the outside area inwards and from the bottom upwards.

• Apply the wax using firm pressure in the direction of hair growth and continue the application in a figure 8 motion. Ensure the hairs are scraped firmly into the wax especially if hair growth is short, stubborn or has been shaved. It is important not to tentatively “paint” the wax onto the area as this will result in the wax not adhering to the skin surface and hair breakage and skin bruising will occur.

• Extend the wax patch onto the surrounding hair free skin; this will provide a lifting edge on hair free skin, which helps remove the wax more comfortably; The extended wax itself becomes a “handle” where the wax patch is lifted off without having to “flick” the wax on the hairy parts.

• Brazilian waxing treatments commence with the standard bikini figure of 4 waxing position before moving on to the genital area. If it is comfortable for your client, ask her to bend her other leg out so you can work on both sides at the same time. This will speed up the treatment.

• If required, ask client to hold her knee bent backwards towards the chest. The other leg is straight and flat. This position pulls skin taut and allows you to reach hairs towards the buttocks.

• Care is required with application in the area above the lip fold join, as three directions of hair growth meet here. Ensure each growth area is waxed separately. Note: if you are unsure which direction to apply the wax, we recommend application in the “majority rule” direction, i.e. the direction most of the hair appears to be growing in. Any remaining hair can then be removed with another application.

• For hair removal around the buttocks we recommend placing your client into the “recovery” position, i.e. lying on their side, top knee is bent towards the chest, bottom leg is straight and horizontal along the couch. Client then lifts the buttock cheek moving the G-string away enabling you to apply wax to the appropriate area. Do not apply wax to the sensitive membrane surrounding the anus.


• Wherever possible, skin should be supported either side of wax patch. This may require both therapist and client holding the skin. If the skin is not taut, bruising can easily occur;

• Removal action should be swift and confident and may require some physical strength. This technique will significantly minimise client discomfort. Hair growth in this area, particularly if the client has never waxed before can be strong and stubborn;

• While providing support to the skin, if your hands are slipping due to oil on the skin or your gloves, use a tissue to assist keeping the skin taut. Remember, the tighter the skin, the more comfortable the treatment will be and subsequently you will obtain a better result;

• Patches of wax can sometimes break “mid-pull” due to the strength of hair or incorrect application of wax (too thin, uneven thickness). Do not attempt to pick off wax and continue removal of broken patch. Use the “handle” from the other end and pull in opposite direction.

• If a patch of wax is remaining on the skin due to drying or breakage, apply more wax over the top, ensure both patches meld together, then remove.

• Our aim in performing a Brazilian wax is to achieve hair free results quickly and with minimal client discomfort. Work with confidence and do not act tentatively, as this will cause the client to feel uneasy and nervous.


• Tweeze any remaining hairs;

• Apply a combination of soothing gel (we recommend aloe vera) and after waxing lotion to the entire area;

• Depending on skin heat and reaction, a cold compress may need to be applied.

• If you think it is necessary, you can ask the client if they would like to inspect the waxed area. If the client’s expectations of the treatment have not been met, perhaps they wanted more hair removed, invite them to discuss this with you prior to finishing the treatment.


• Advise your client to treat area gently for 24 hours, for example, no strenuous exercise, tight clothing, heat treatments, e.g. sauna, steam room, jacuzzi or sun tanning;

• Use a mild antiseptic wash for 2-3 days if they have a tendency to break out;

• Advise client they may experience some itchiness when hairs are growing. This can be minimised with moisturizers and gentle exfoliation;

• Educate your client to use an exfoliant to prevent ingrown hairs. Preparations are available to minimise and treat ingrowns.


• Regular waxing will reduce regrowth considerably. We encourage you to re-book your client’s next appointment before they leave.

• Re-waxing the area normally is done every 3 – 4 weeks, however, regrowth may diminish after several treatments

Reasons to Choose Permanent Makeup

Permanent makeup is a somewhat older type of technology that has continued to stick around. Permanent makeup classes teach those who tattoo to put ink on the face that looks as if it is makeup. While some people may seem permanent makeup as a technology for those who are lazy, those who take permanent makeup classes are not thinking of that; they are thinking of those who are unable to apply makeup on their own. Those who have trouble can be helped by permanent makeup.

Eyesight Problems

When it comes to makeup, eyesight is key. When people see bad makeup on someone, they will often ask themselves if the person can even see themselves. Some people have trouble seeing, and therefore have trouble applying makeup. Permanent makeup classes teach people to apply makeup so that people who have trouble seeing can consistently have the look of well-applied makeup.

Steadying Problems

When some people go through permanent makeup classes, they may not realize who they are helping. There are people, both young and old, that have trouble staying steady. Some people have conditions or problems that cause them to shake. Anyone who has tried putting on makeup while shaking will realize how hard this can be. Permanent makeup helps those who have steadying problems have a complete look, with makeup and all.

Allergy Problems

Those who have had allergy problems with jewelry will begin to understand the problem of those who are allergic to makeup. Some people are allergic to makeup, generally because of the materials in the makeup. The way that their bodies react to the makeup means that they cannot wear it. Permanent make up classes and permanent makeup can help these people to have the look of makeup without the actual makeup. Because they are not allergic to the ink that is used to tattoo on the face, they can handle the ink, and their bodies will not have the same issues as with makeup.

When it comes to simple, everyday tasks such as makeup, people tend to forget those who cannot do them. Because it is such a normal activity, those who cannot do it are often frustrated. Permanent makeup classes allow people to do more than tattoo makeup onto the face; permanent makeup classes allow those to help out people that have issues applying makeup.
